No, higher. To the right. Right there. Little higher. Yep, got it. Researchers have identified a protein present in all mammalian semen —camels, weasels, bats, bunnies, piglets, horses, blue whales, and humans that's all the mammals, right?
It's called nerve growth factor NGF if you're nasty and it's typically found in nerve cells, where it regulates nerve maintenance. By day. According to Morgentaler, "guys are into quantity and not so much quality. We are talking two heads, two tails, big heads, small heads, big tails, small tails, no tails… it's a hot literally mess sometimes literally.
Sperm does not begin to form in a male's body until he hits puberty. By that time your body's immune system has already decided which kinds of cells are part of the human body and which are not. That means, according to Morgentaler, that left to it's own devices, your body would attack sperm as an invader. That's why the testiciles are shielded in many complex ways from the rest of the body.

I used condoms with my two subsequent boyfriends, and the sex was pain-free bliss. I could walk upright within minutes! I could speak to someone an hour later and not still have a wet washcloth in my pants to cool the burning. That's how I learned a frosty can of Bud Light is a perfect ice pack for your crotch. Yep, the searing pain surged right back. Tears leaked out of my eyes as I struggled to breathe through it. No other area swells up or develops a rash.
