Awesome pics! To answer your question, it really just depends. As far as women who have been initially attracted to me because of cock size, I think that can only happen on the internet or a nudist club or swinger club. Through aff, here, Cl and a few chat lines I have met several women and had a lot of fun and they responded because of my pics. I've also had several couples contact me structly because of the size issue.
I think unless a woman is out there gazing at our crotches all day, I don't know how they could know for sure ;-).
If I'm with any woman who is vocal, the size comment comes up. Most find it a bonus, a few a must, and some said they liked how I used it and weren't hung (pun intended) up on size. My gf says she can never go back now lol.
I've had a few who couldn't accommodate me, and found it painful which is always a bummer, so there is the occasional negative reaction, but I certainly wouldn't change anything.
