My first time was brilliant!
I got my first time topping and bottoming out on the same night.
I was with my first real boyfriend, new at college, and it finally came around to having sex. I knew he was huge, and he'd bottomed before, so he let me top first. I remember as soon as I slid it in I was overwhelmed by a feeling of....apathy. It was anticlimactic. I don't know if it was being nervous or what, but it really didn't feel terribly different from masturbating. (In later sessions, though, I grew to really enjoy it!)
Once that was over, it was my turn to bottom. He had never topped before because none of his partners before me could/were willing to take his size. I was strangely at ease (probably because I had just cum not 10 minutes before) but he put me on my back, ankles on his shoulders, lubed himself up and put a little on me, and started to slowly push himself in...but I wanted to get it over with, so I told him to just slide it all the way in and hold it.
I nearly came right then and there! It was the most amazing feeling!!! Much better than topping

I was clearly doing something right, though, 'cause he converted from being a bottom to being a top right then and there!!! Needless to say, I'm still a bottom (although I still enjoy putting it in other guys' butts from time to time, too).
So awkward? Not at all! (although cleanup after was awkward...there was lube and cum everywhere, and neither of us knew what to say

)
*****
A friend of mine (technically an ex, but it never turned into anything serious) asked me last summer if I'd take his virginity, since I had experience and he trusted me. I agreed, and we got a hotel room, and it was SUPER awkward from the minute we started making out. He was SOOOO uncomfortable, and NOTHING I said or did would calm him down. It FINALLY got around to fucking him- I told him it would be best if he lowered himself on so he was in control, but he said that was skanky and that he wanted to be on his back facing me...I had barely put the head in, and he freaked out and left!!! I now have a strict policy of NOT taking Visa (if you know what I mean).
