Unhealthy obsessions with men

Well it seems to me that you have a very high sex drive which is completely normal and a strong desire to be loved by another which is again completely normal.

One problem you do seem to have is getting emotionally attached to people before you really come to Know them as people or developed to much of a relationship with them. For That I can only recommend counselling.

there are however some things for you to consider.

1. casual sex. It’s probably very easy for you to get And would help you to scratch that itch without putting yourself in a position of being abused or exploited. Provided you keep it sex only. However given your  Predeliction  for getting attached I think you’d find the emotional toll too difficult.
2. i’ve sometimes heard it said that those who appear to be vulnerable attract those who would wish to abuse. It’s possible that manipulative people are attracted to you as someone they believe is easy to manipulate. One way to negate   this affect would be to actively seek a romantic partner. Do not wait for a man to select you and show you some kindness. Flip the script. Go out there and try approaching some men. Maybe try speed dating. You don’t need to worry if a man has selected you and approached you because you have victim vibes if you are in fact the one who selected and approached him.
3. you need to develop a sense of the kind of man you are compatible with. People with similar interests people who complement your points of view and the things you enjoy. Kindness is a wonderful property. Everyone should require that their partners be kind. But for most people it’s not enough. If you select potential partners who have these extras, the special criteria that some people might require for thinking there is  a relationship in it, then you have a better chance of them reciprocating your feelings.
4. there’s absolutely nothing wrong with wanting to be a glamorous and ample breasted woman. If it makes you feel good about yourself to spend time dressing sexy or making your body look sexy then why don’t you do it if it improves your mood. although I would emphasise it is best if you do it for yourself rather than because you think it will attract men.

regarding  The role  autism  plays  I will say I do think autistic people do tend to get attached early on and quite easily. I think if you experience social isolation you are always going to be a little bit desperate for social contact with others and you’re going to tend to latch onto those who Enter your social sphere more than other people might. I also think sex has a special interest even among prepubescent autistic children is probably far more common than most people expect. All children are attracted to secrets what is hidden what is forbidden. But autistic children do not see the non-verbal social warning signals saying ‘this is really bad you shouldn’t really get involved in this.’ More to the point it’s just pretty interesting. And since pretty much every human being goes to a phase when their hormones are really high and sex is constantly on their mind, it’s not surprising a lot of autistic teenagers would also develop a special interest in sex.

With a lot of respect to your answer, it still doesn't scratch the surface of finding a solution for this. When it's one negative incident then small changes can help, when it's a life cycle of obsession and abuse then only therapy can help.
