It's a case of using your sexuality to get whatever you want (within reason), being introduced to drugs to help having sex with men easier and funner, then getting hooked, resorting to some petty crime escalating to more serious stuff because of your lack of getting drugs and wanting more and/or the effects of you being on drugs making you behave irrationally/violently/etc. It's all just a downward spiral.
I rented him several times starting about 10 years ago. Never when he became so drugged out looking but partially during the start of his rap sheet. I lost touch, and didn't want to reconnect anyways when I saw how he unraveling. But damn he was such a gorgeous, enjoyable and sensual boy. Fast learner, not necessarily obedient in terms of being commanded but would oblige a lot of things under the right terms. Enthusiasm was fake or non existent for certain sexual acts and more genuine for others.
IMO, it was a bicurious boy who realized he liked certain kinds of men for certain sexual stuff and for others he needed money and substances to get through. Sometimes just the promise of the drugs was enough to get him in bed. I just gave him money and some weed/poppers/g/tolerated his coke use a couple of times. I never liked doing more than that with him or directly contributing to anything more (like crack, meth, or whatever he did with other guys/in private). I steer clear of that crap. Only once was he seemingly on something more serious, which was when I realized things weren't going to be the same from then on.
Sex that last was time still good. Just a tad more concerning about his state and more like screwing a gorgeous muscle intimate object.
