Straight-Bi or whatever one claims.....It does not make one come across as gay if anal play is involved, it's all in the head and what one enjoys.Common sense rules.
I'm a Bi-Sex guy, like it both ways, if I'm condemned for that So Be It...It's my body and I do to it what I want and what feels good. So, guys jump off the scared train and jump to the fun train, but then again it's what one likes or dislikes, if you like your butt played with then have at, if not then just don't do it. Plane and simple.
Read, study, research----and see what the doctors say about anal dilation, over board play can damage you, but if one goes at it using both heads to think then it can be a pleasurable experience.
I've just got into anal play in the past few months, going at it slow and easy on the size, so far UMMMMM, like it, up to a 1.5 inch size. Feels great when coming out a very good pleasure, all kinds of sensations I have never felt.....
Play, be easy, go slow, and use lots of lube.
