Hi. I want to offer my 2 cents here on this subject...

in all honesty you should quit doing what you are. you are here talking to us about it, as you know that it's not healthy and is extremely dangerous, especially since you are going thru some form of intimacy with these guys, some may get angry and take it out on you as if you are leading them on, like a c**k tease.
your doc may be wrong here as you may have left feelings out or details, that may make them have a different take on the matter.

you should just find a med that curbs your libido, or get a vibrator or both.
I understand the need for affection and human touch. (I have been celibate for 6 years) so, yeah I get it.
but being beaten up, raped, or other things, is not worth what you are doing.

please consider getting some serious intervention here with your doc, and if you feel they are not getting what you are laying down, make it really clear to them, even if you break down in the appointment and start bawling. they have to know what's really going on.

also, just because you are not going that far with them, doesn't mean that they won't stalk you. keep that in mind.
good luck with this and I am here if you wanna talk. let us know the outcome and how you handle things going forward please. /hug
