Same as the guys coming on here and saying.... How do I convince my g/f to let me do her up the butt..lol.
There really isn't any "convincing"... If you want, bring up the idea... but don't push the issue or make someone feel guilty about something they aren't comfortable w/ doing.
If they ever get ready... they'll let you know.
Just putting the idea out there is good... maybe the guy is interested in trying it... but thinks his girl might see it as gay... if he knows you are cool w/ it... then he might be more open to it.
My b/f asks me to do this to him... but I'M the one that isn't really comfortable w/ it.
