Doggystyle! I have written about this position before but this time round, I'm gonna focus on what you should do with your hands. This is from a guy's point of view by the way.. and this info is aimed at guys.
This here is based on my own experience. Hopefully, Rudo will add her two cents. I am very familiar with semen lol so I guess I'm very qualified to speak about this. Yes, I have tasted it and even swallowed it in case you're wondering.
