I an ardent fan of oral sex, and I tremendously enjoy both having my dick sucked by another guy and sucking other mens dicks. Aside from all the enjoyable aspects already listed, I offer an additional commentary. A mans genitals are the very center and source of his manhood. Ones face is a highly individualistic part of the body and is where all the human senses come together, such as sight, smell, taste, and touch. The meeting of these provides an enormously sensual experience, where a man is savored by his partner in a carnal and intimate way that is different than other modes of sex. I very much enjoy most or all types of sexual contact, but, for me, nothing is hotter than the classic 69, with two men hungrily feasting on one anothers most male-defining feature. Bon Appetite.
