Just a gentle reminder which I hope you find helpful, but being turned on by BDSM and wanting to be used are two different things. There are lots of couples, LGBT+ or straight, who use BDSM as part of a loving, caring sexual relationship, and there are also a lot of people who have fantasies to be used and objectified by complete strangers without BDSM as part of the scene. There are also a lot of people who want both. So regardless of which category you fit into and whether you feel these feelings are normal or not (and my strong opinion is they’re normal), you’re certainly not alone.
These feelings may or may not be created or strengthened by CSA. There are certainly many who were not abused as kids who have these desires. I believe in general it’s ‘normal’ and can be healthy within limits - I believe that people are attracted to risk and excitement during sex as a way to get the adrenaline flowing. Whether or not one takes it too far is another matter, and if CSA fuels this desire to such a point and you feel it’s not normal anymore, you can get help from a therapist.
I might be wrong with this assessment but want to share in case it helps. There are also a lot of bi men (my husband is one) who aren’t equally attracted to men and women. It’s perfectly normal to be romantically attracted to only one gender but sexually attracted to both, or to prefer one gender much more than the other. It’s also normal to have different types of sexual relationships with different genders, e.g. cuddly romantic stuff with women and ‘we’ll be unrecognizable after’ debauched stuff with men or vice versa.
There are also a lot of LGBT individuals that really downplay the importance of male-male intimacy because we still live in a society that has a lot of negativity towards LGBT people, and it’s impossible in my opinion to be unaffected by that. A lot of people channel that negativity into risky behaviors or depersonalizing sexual situations.
I don’t know if some, all, or none of that applies to you, but I wish you some peace in unpacking the feelings you have, and thank you for sharing here.
