Back to the subject.
First off, it is in no way gay to enjoy strapon action. Having a guy stick his dick in your ass is gay. Having a woman do it with a strapon is just kinky. I disagree that it is something that older guys won't consider. As one of those who passed his half century a few years ago, I find myself getting more and more interested in the kinkier side of sex.
A few years ago I let a woman peg me. It wasn't something that I had even considered before, but I let her because it was a major box to tick on her bucket list. To be honest it was painful and not particularly pleasant and I know now it was because she really didn't know what she was doing. About a year later I went to see a professional and agreed to try again with her. She knew exactly what she was doing and it was bloody brilliant. I mean just one of the best sexual (maybe even the best) experiences of my life. In case you are wondering, this is the lady

The point I think I'm trying to make is that life is too short to be conservative. If it interests you then who gives a damn what anyone else thinks? Sue is exactly the right kind of person, with all the right skills, to see about this as she totally gets that guys are basically kinky sods. She also gets a kick out of doing it and that is exactly who you need to break your anal cherry.
If the very idea of exploring your sexuality turns you off then don't do it. At the same time I ask that you reserve judgment if you know nothing about it.
