So being well endowed, and knowing quite a few of my well endowed breteren, I can saw it sometimes CAN be a curse, it all depends on how you approach it. One guy I knew (I'll call him Jim for the sake of argument on here) was a great guy. Very attractive, very nice, and hung close to me (I was longer, he was thicker...and that is THICK). When I first met him, he was shy and a little intimidated to be getting a lot of attention. Two years later he was totally jaded. No one wanted him for any other reason except for his big dick. He never saw people as people any more just someone to fuck. Some five years after that, he was still single, lives in an apartment in a dead end job by himself. Oh and is online every day talking about his dick and how lonely he was. I stopped talking to him it was tooo depressing and he wanted NO advice.
Another guy I knew, hung bigger than me, sweet guy, turned into a total introvert. He shied away from the attention and stopped dating. Last I knew he was single, upset he was single, but would NOT go out at all. Smart, witty, a great guy, HUGE dick, and totally in the closet about his cock. I think he got burned on a relationship that was based ONLY on his cock size.
Last story. One guy I knew who was a total bottom and who was hung similar to me had a problem finding someone to top him. NO matter THEIR size, as soon as they saw him they wanted HIM to fuck THEM. He could not function as a top and it was a total failure. As it was he was thrilled to find me! We kept up a healthy sexual relationship (sex only) for over a year. I have no idea what happened to him then we drifted apart. I hope he found the hung top of his dreams! MAN could that guy btm!
In the end, yes having a big dick is nice, but you have to work with it like any other asset and minimize it in some circumstances.
When I would date for relationships, I would change my profile to just a description of me - nothing about my cock, and NO SEX until date three or four. It weeded out the weirdos. Also though my partner and I can't have sex, size was never an issue (he dated guys MUCH larger than me) and I always appreciated that. LOL - and when he could still have sex, he still loved my size, but it wasn't the driving force behind the sex.
So be who you are, your cock size is just an added bonus. Don't give it away on the first date ;-)
