I suspect we've strayed off topic, albeit in a good way.
The way I read phantom73's question is this. Endowed men have such trouble finding condoms that fit, do they give up in frustration more often, or have regular accidents? That puts them at special risk for HIV.
I gather from the collected posts (and from my own experience) that while there are accidents and exceptions, most well hung men would rather enjoy imperfect safe sex than perfect unsafe sex.
Let me share for a moment. One of my first male lovers was HIV positive. He confessed this before we did the deed, and having graduated from a Gay 101 course at the local gay men's health centre, I was confident that it could work. And it did.
Not so my old boy's previous lover. He was a well hung gent, who got so frustrated with condoms--and was so confident that an exclusively top guy couldn't be at risk--that he abandoned safe sex, over my old boy's protests.
My ex-lover lives. His ex is dead. When I met him, my old boy was a mess from the guilt, even though the unsafe sex wasn't his decision. Little consolation when the doctrine of love says you must proitect those you care about.
My ex wouldn't LET me practice unsafe sex. Even though he wasn't the one at risk. Surely, that's what love is about?
By the way, emotional messes, safe sex and uncomfy condoms as part of the deal, I don't regret that relationship for a second. We're still friends, and I wish him and his life-partner a long and happy life together. IN fact, I take some pleasure in knowing that I may have helped; when we first met, my boy had abandoned his HIV regimen out of guilt and shame, and I took no truck with that. Gay 101 makes you pretty bolshie about that sort of stuff.
Thanks for starting this thread, phantom73.
