I'm an 18 year old male. At times at home online, I get these uncontrollable sexual urges. It makes me really really horny and my brain just kind of goes bye bye. It often causes me to say things I normally wouldnt to girls...you know, sexual things that I later regret, and angers them. Its strange and I have no idea where this comes from. Can anybody give me some advice? How can I stop this?
