Been pegged a couple of times, needed to try it after mad nat fingered my arse a few times, so decided to take a pegging, can only recommend go small with the toy, lube up, relax and above all make sure the girl knows what's she doing.
I enjoyed it having my ass slapped and pulled onto a small strap, but most I enjoyed the idea of it, the wrongness of it and the girl talking filth about it, i.e. If your wife could see you now, taking it up the ass etc.. I loved being on my back watching her tits bounce as she thrusted ,and she wanked me off however after tried it never had it again itch scratched and no
I don't feel gay.
I see it as like with other things I had explored my sexuality and ticked it off along with ffm, water sports, and others and enjoyed it.
Have no desire for sub, Bdsm or pain or hardsports but glad I tried it pegging a couple of times, and glad the girl used a small strap
Go for it and if anyone gives you shit and bollocks being gay, ignore them just be comfortable that your exploring your sexuality and see where it takes you
