I don't know and I don't care. I just prefere my body and the bodies of my partners totaly shaved, a little bit pubis hair only. I don't feel this less masculine, only much more refinated as a body. The body hair is not what makes you man.
As teenager I was forced to blowjob 2 guys in a abandoned building. They allured me there. I was skinny and shy kind of boy and they was older, bigger and stronger. I refused but they was gross, they hit me and they threated me that they will beat me. Anyway I had already homosexual experience I was very scared and started to suck them both. My fear made me suck them and made them cum very fast. They forced me to swallow the semen. They was very satisfied one of them even kissed me in the mouth and touched my cock. Not sure I like or not that anyway.
The first time anal fuck experience I had as a teenager. It was really painful and difficult but only in the begining. After some minutes I liked the felling to be filled a lot. The cock of my partner was not very long but thicker than my wrist. We was fucking each other regulary for months.
