I think guilt is a mostly useless emotion. Especially in situations like this, when you alternate between "sin" and "guilt". One does not stop the other, then what's the point?

I think you have the total right to engage in whatever activities you like and no one can tell you otherwise (assuming you are not cheating on anyone and secure a consent of the people you engage in the activities with). If there is God, I hope he is busy fighting Ebola right now. I don't think you personal sexual life is of such a tremendous concern for him. And if God would curse you for being ill and having hyper-sexuality as a symptom, we are all doomed anyways.

However, you need to take precautions to keep yourself safe. Never have unprotected sex, never go anywhere with people you don't know without alerting someone to your whereabouts and making it known to the person you are with that your friends know where you are and will call police if you do not turn up. Try not to have the outright "sex" with people you just met. Limit first encounters to the activities that will not leave anyone pregnant or with a disease (I'm sure you can come up with the couple alternatives).

Don't make yourself suffer needlessly. You have a lot on your plate as is. Keep safe and have a little fun. It's your right and no one can stop you unless you are breaking the law.
