Hi there. I hope I can help.

Firstly, do let me apologize for everything going on...I know this can't be easy for you. I do agree that it sounds very much like abuse, though I couldn't tell you any more than you could about the specifics. I do confess, and please don't take offense...do you think there's any chance your father and what he's going through could be related? As I said, no offense there, but I don't think I'd be helping if I precluded that possibility, horrible as it is.

At any rate, sexual abuse victims vary in their responses to the abuse in regards to the libido. Some report losing their sex drive, as avoidance to sex removes the possibility of that ever happening again, or link the trauma too much to sex in general to have a sex life after the event. That is one side of the spectrum. Others can actually increase or alter their sexual behavior, which I think is what your brother is doing. Based on everything you've said, it sounds to me as though he was abused by a male, and is thus trying to "normalize" his experience by throwing himself headlong into this. That is of course purely my speculation, and I hope I am as wrong as I can be.

As far as therapy goes, you can't force him to go. Even if you did, he has to want to be there to get help. Otherwise, he will simply go through the motions, or worse, remain unreceptive to the treatment. You can't force him, though you can convince him. Explain that you love him, and that you're concerned for him, and you think that therapy might be able to help him. Explain that you only want him to feel better, and you think right now that he is suffering. That, I think, is your best shot.

Please know that you and him are both in my prayers. I hope for all the best for you both.

My best,
Harley
