Giving head and receiving a hand job.

Sucking another man off and swallowing his sperm is definately my all time favorite sex act. It is exciting, rewarding, fulfilling and, yes, even empowering. The knowledge that I am controlling another man's orgasm is wonderful. And I like to take his sperm. It's good to know that his sperm will go down into my gut, be digested and turn into muscle tissue in my body. Part of him will become part of me.

A close second is being sucked off. It's nice to be able to give another man my sperm.

Jacking and being jacked are distant third and fourth.

Just the thought of jacking another guy until he cums is a real turn on. We did this when younger and it was exciting times

I think I like giving both the most
