this is easy for me to say because I wasn't raised religious but try to remember that showing skin is not promiscuous. conservative men want to portray it that way because it makes THEM aware of urges they want to pretend they don't have, but it's just clothes. you're not doing anything "whorish" by dressing a certain way. (not that there's anything wrong with acting like that if you want to, but that doesn't sound like it's your issue here)
Real talk: Look your sexuality straight in the face. Doing so helped me a lot. Listen to sexual songs, read smutty fanfic, anything you are comfortable with. Also, if you’re trying to get more comfy with your body in general, I suggest practicing at-home nudism if possible. Sometimes just chilling out in your most natural form can heal something in you.
