I'll try and keep this brief and as straight to the point as but would like to share my thoughts and feelings as much as I can. First of all I'd like to introduce myself. I am a 28 year old and currently in a relationship with an amazing girlfriend who is very open when it comes to sex and is very willing to do things to make me happy (even though I can be shy at times) I can trust her 100% and she has no reason to lie to me as she has shared things with me that I would rather not know but she is always honest. I have a fetish for big dicks and it started from an early age, around 17 I guess and always felt like I was inadequate or was never 'big enough' down below. I have always been into watching porn and like nothing better than watch a huge guy (usually a hung black guy, hence my username) and I'm not sure if watching all this porn has made me feel insecure and paranoid about my size. Back to me and my partner. I currently have been doing PE for about 4 months now and my girlfriend caught me in the bath using my bathmate which was rather embarrassing and told me that I didn't need to do and it I should stop doing it, she also said she loves my cock as it is. I must admit that it does work fine and have never had erection problems or premature ejaculations but its always been about the size for me, especially the girth. I'm just over 6.5" BPEL and 4.7" EG. I always make her orgasm and it has only been a few times where I haven't made her cum and she does get very angry and boy do I know it, lol. We have played around with toys ect and decided to treat mysef to something and got this Three Extra Inches Penis Extender Sleeve - Penis Extensions - Lovehoney Mobile I was a little bit coy at first introducing it but she was keen to try it and make me happy. She managed to take it well and it was so horny to watch her take it all. With it on I was about 8.5/9" long and around 7.5" girth. It was an amazing experience and we have used it a few times but she says she prefers mine. We have both shared experiences and the inevitable topic of 'What's the biggest penis you've had' conversation which I'm sure I'm not the only guy to have talked about this with their partners. Anyway, she told me that her ex-husband was the biggest she has had and I have known this guy for a long time as I used to date a girl many years ago who was friends with this guy and I always had a slight crush on the girl I'm now with. Its very confusing I know. He's not like my best friend or anything but we get on ok and now currently play football with my girlfriends ex-husband. As we were talking about sex the subject of 3sums come up and she said she would like to watch me get fucked by another guy and I said "that's he'd have to a big dick", and she said that her ex-husband was big. I agreed to this as I was really horny at the time so she sent a few texts to her ex asking for a pic and if he'd be up for it. He agreed and replied with some rather horny scenarios and he sent a pic of his cock. I asked to see it and it was slightly impressed but the way she talked about it I thought it would be much bigger. She said she measured it top be 7.5" long and over 5.5" thick. It was a nice cock and we talked more about it and she seems up for it. My question is....... Is it worth sacrificing a fantasy for what could be a lot of emotional pain and maybe jealousy if I do decide to go through with this or is it one of those things that are best left as a fantasy? If anyone has had a similar experince I'd like to know what happened and how you felt after. Not as brief as I thought but I thought I'd let you know as much as possible about my life so you can give me advice ect. I will post a picture of me as well and I'd like your honest opinions if you think I'm crazy. Thanks guys and gals.
