I love that little shot of adrenaline manufactured when my lover is holding me down and his penis is blocking my airway. Its better than a roller coaster. Logically I know that in a second he'll let me take a breath, but million of years of evolution have conditioned us towards self-preservation. My body reacts involuntarilly and I try to pull away and he holds me a few seconds longer before letting me go.
I enjoy having him come in my mouth, or in my ass or cunt a little more than I enjoy being ejaculated on. But so long as it's not in my ears, eyes, or nose it's all good. It's even better if a girlfriend cleans me up afterward-- lips and tongue, not a washcloth.
Dont mind either luv guys wanking and "shooting" over my face or have him in my mouth and let him cum in my mouth and suck and swallow every drop and keep sucking until it is clean.
