Heya, sorry but I don't have enough time to PM you.
I was abused as a child so if thats what you are referring to i know from experience how awful it really is.
My advice is do whatever you can to not be alone in the room with whoever the person is.
and maybe if you are young person in highschool, see the school counsellor about your problem, they are meant to keep it secret, but you can ask them not to tell anyone to make sure.
Also there are kids helplines etc that you can call to help you out, about any problem.
If the problem is that you are wanting to have a relationship with a family member?? I would say don't because that just doesn't seem very healthy... anyway hope you pull through, just stay strong no matter what crap in life is bringing you low, thats my motto 3nodding
if you happen to have a crush on a sibling or something, dont worry too much, its (sort of) natural BUT the thing is you dont really love them romantically. its like a mindtrip, sounds like Im full of crap but it does happen.
If its sexual abuse you should stand up against them. they exert their dominance on you so what would be so bad about dobbing on them and taking the upper hand
