Yupp, it's all about the testerstone! The male hormone. Male have both testerstone and estrogen (female hormone), but have more testerstone, when a man become old, such like 50 or 60, testerstone decline and the estrogen increasing sightly. Now you wondering why older men have bigger tits compare to young guys
Agree with your post! 
*nods* I felt the same thing, I feel quite used before.
Hmm, our penis will get hurt if we sex too much in a day. Plus we, males, do get exhausted if having too much sex.
Wow, thank you for a awesome post! Of course I won't give up.
As for your question, well, I gotta admit I did have sex with those guys but it was long ago, and you are correct, I was drunk and ended up have sex with those guys. But they still want it again, and I try my best to not play with their heart or let them do it. We are good friends, we always understand each other, but I am just getting bored of them being obessive about the sex that's all.
