I agree with Miss Petite, that it isn't the blessing that being rich might be. I'm only fairly big, but I've been with guys who were huge, one of whom had a cockhead so big I could barely get it in my mouth. Now I'm a great cocksucker (I've had reviews!) but I couldn't give this guy a particularly good blowjob or use any of my usual tricks. Fortunately he was a bottom (weird how random that is...) as there was no way I was letting that inside me!
I'm joking about it now, but it occurs to me that that guy probably never gets a particularly good blowjob off anyone, and if he was a top he'd find a lot of guys wouldn't bottom for him, and I'm sure many women would feel the same way. And I hate to say it, lovely gorgeous guys on this site, but the difficulty with his cock might have been a contributory factor in me not making any special effort to see him again.
Now if I'd been in love with him I'm sure we could have found a way to make it work, but in those early days its easy to make a decision based on a trivial difficulty that more established couples can work out (like living in different cities, or having different incomes). So I have sympathy with anyone who says there's a downside to having a big, visually appealing dangler to show off in the shower!
