Lostboy saidBB is so totally ewww
It's also so totally suicidal, if the OP hasn't been in a totally monogamous relationship with this guy for at least 3 to 6 months, and then both been confirmed negative at the end of that period by standard HIV tests. And I have no information how a PA can affect the integrity of a condom, especially since I don't know its shape or size.
On a lighter note about size, I once dated a guy with a huge PA, biggest I've ever seen before or since. I wouldn't have considered anal with him for a second, and oral wasn't all that much fun.
That damn PA clanged against my dental filings something awful, and all my usual techniques of tongue & mouth wouldn't work as well. I asked him if he'd like to remove it, which I assumed he could do without a blow torch, but he wouldn't consider it. Too bad, and his loss as much as mine, since I give a great BJ when I don't have to deal with a metal shower curtain ring in my mouth.
