Once again, thanks for the reply.
The medications are all long term stuff, going back years, but the issue existed before the med's became involved that why I ruled them out as a root issue.
I'll have to look more into testosterone and read up on peoples reviews of how they felt after going through the injections and what have you.
As for attraction and turn-ons, that's sort of complex. I've never really had urges or desires when looking at the opposite sex (or the same sex) in general, but I can appreciate ascetic beauty in some, while finding others less so, but it rarely results in any form of arousal, which I'm led to understand is common in men.
I've found that for me, sexual attraction is mostly linked to my having an emotional connection as I find women I've gotten to know and understand are more sexually appealing than any random woman I might see on the street, for example.
The woman I was briefly involved with recently was very physical and sexual (She was Italian and lived up to the stereotype about being passionate), and we had a lot in common interests wise, but even though I was aroused by her (Erections aren't really an issue), I still felt nothing physically (Not 100% accurate, there was no penile sensation, as I mentioned my issue was, but I could certainly feel light feelings akin to gentle tickling in the surrounding areas) when things were happening. It really put a dampener on things, since she loved sex and saw pleasure as a two way street, but it was all one-sided for her.
Prior to her, I was in a quasi-intimate but emotionally deep relationship with a younger woman for four years (She was Chinese, smart as hell but due to strong traditional and familial values she was under a lot of pressure for dating a white guy so it wasn't working out) and again, while I could react to her, I didn't feel anything physically.
I have tried various means and methods of masturbation over the years, and utilized various sexual aids too. I've tried things like the Fleshlight and similar male masturbatory tools, including various vibration devices, none of them felt like anything to me either.
As to being careful, well when I was in my late 20s I actually managed to tear my frenulum after a prolonged session of attempted masturbation (Was approaching 30 minutes and I was getting bored an irritated, not a good mix) so I know about hurting myself with trying to find something that works, to no avail.
