Last weekend I went on a brief trip to an eastern European city with three of my university friends. One of them (let's call him Ben) is also my friend from school, so we've known each other since teenage years (we're both now 36). I was the best man at his wedding; he is straight and I'm gay (and out to him). There were two of us to a hotel room so I shared a twin room with him.
When we were at university we used to swim together regularly, and would shower naked afterwards in the communal showers, and change together without inhibition in the male changing room. On one occasion when we were 20, I also went skinny dipping with him and his then girlfriend (now wife) on a deserted beach at twilight - one of the very few times I have been completely naked in front of a woman.
When we got to our hotel room I needed a shower, so one of the first things I did was to strip completely naked and walk to the bathroom in the nude. On the way back I wore a towel but took it off to dry off in front of him. Later he returned the favour by stripping off himself completely before heading to the bathroom, though I only saw him from behind.
When it was time to go to bed I wore boxers, but slid them off under the covers to sleep naked; he wore pyjamas, as usual, though he did change into them in front of me and I briefly caught a glimpse of his cock.
In the morning when we woke up I had a "sod it" moment and just cast off the covers, revealing myself to be completely naked (a bit chubbed up, but not hard) and then casually walked to the bathroom nude again. On the way back I chatted to him while rummaging through my rucksack trying to find my boxers, all while completely nude facing him.
He then headed off to the bathroom nude (though again I only saw him from behind). On the way back from the bathroom, though, he just walked completely stark naked, cock on show, back to his bed and I saw everything, full frontal.
For me, the uninhibited nudity was hot and I've wanked over it several times since, but it was also just really nice to have a close friend with whom we can both be totally naked without any shame or embarrassment; I think there's something quite special about it. I love how he doesn't mind me seeing everything, and isn't creeped out by me seeing his cock, despite knowing I'm gay (and also knowing that I used to fancy him!).
So since the above episode I've had two further trips with this friend. On both occasions we've shared a room and there was a lot of nudity.
On the first trip (six months after the one I posted about, above) the ensuite bathroom walls were actually made of glass, so you could see right into it from the room, although there was a curtain that could be pulled out for privacy. We didn't notice the curtain at first and I remarked that it didn't matter because it was "just us" and we'd both "seen it all before", to which he agreed. However, we did notice it before either of us needed to use the bathroom (which was perhaps a shame, although perhaps not when it came to sitting on the toilet).
Anyway, on that trip there were many homoerotic moments. The first was when we were undressing for bed and he took off his boxers while still wearing his T-shirt, but continued to talk to me for about five minutes in that state (i.e. with most of his cock on show, poking out under his T-shirt) before putting his pyjama shorts on. During that time I stripped down completely naked to change my boxers, so that there was a moment where I was totally naked in front of him, and he was partially naked in front of me, with his cock showing.
On one morning I had just finished on the toilet when he emerged from behind the curtain, bare chested but wearing pyjama shorts, and just walked straight into the bathroom saying he needed to piss. This time, I was wearing a vest but nothing else, so my penis was totally on show. I said that was fine and gestured towards the toilet. He then proceeded to have a piss while I brushed my teeth. Then he finished and I moved slightly to one side at the basin, so that he could wash his hands right next to me. Then, he stayed talking to me for another five minutes while I shaved, while I had my cock out the whole time. It was incredibly sexy just how unfazed he was by my penis being on display, and it was a real struggle not to get hard; I certainly did get a bit chubbed up, but that was all.
He left the bathroom before I started my shower; but, on finishing, I realised that I had (genuinely unintentionally) left my towel outside, so I called to him to bring it and he did. Rather than just leaving it outside the door to the bathroom, he came right in and handed it to me while I was totally naked and wet - again, clearly completely comfortable with the situation.
On the most recent trip, in the morning of one day he went into the bathroom to go to the toilet, but then came out again, took his pyjamas off while facing me so that he was completely naked, and walked naked into the bathroom for his shower. When he came out he changed naked in front of me too.
I also slept naked and in the morning threw the covers off and got out of bed and walked to the bathroom naked. Again, this clearly didn't bother him. While in the bathroom, and still naked, I opened the door slightly and shouted to him to ask whether he had any shaving foam (as I had forgotten mine). He then got out of bed (in pyjamas), walked into the bathroom (which I hadn't invited him to do), and proceeded to rummage around in his toiletries bag looking for it. This was all while I was totally naked standing next to him. Neither of us was in the slightest embarrassed by this; it was all totally natural. Once I'd finished in the shower, I walked out of the bathroom naked and proceeded to towel off while talking to him; when he'd finished his shower, he did the same.
Bear in mind my friend is straight; he is married and has a daughter. The total inhibition about nudity is (for me at least) really special. The fact that he is (presumably) not turned on by makes it even more so, in some ways; it's lovely that he is so at ease with me, despite knowing I'm gay and that I have fancied him in the past. It makes me love him all the more!
What I would have liked to happen is for him to have brushed his teeth and shaved while I was in the shower, and vice versa. Maybe next time!
