SF, They don't have to shove.. they can be gentle too
I'm not sure why straight guys equate anything in your ass to being gay ( yes, I have the same hangup sometimes). You have no idea what you're missing out on by not trying this. It probably isn't something you want every day, but when you get it.. oh man is it good. I've actually been sore the next day from the power of the orgasm. The strap-on idea is interesting given enough lube.. I think I'd do it!
