1. Grown women with naturally small boobs, A-Cup or B-Cup only.
2. Large, dark nipples. Small breasts with big, pointy nipples get my attention every time. The areola can be big or small, it doesn't matter, I like nipples.
3. Hairy pussies. The hairier the better. Only little girls have bald pussies, and I don't have any interest in them, don't want to see them at all. Grown women have bushes.
4. Receiving a sloppy wet bareback blowjob with lots of slurping, moaning, deep-throating, gagging, chortling, sputtering, eye-contact, ball-sucking and never seems to end. There has to be so much spit drooling out of her mouth that it costs both my shaft and her hand, and oozes down my balls and puddles at my asshole like natural lube.
5. Lots of sloppy wet deep French kissing after oral sex, but especially after I have gone down on her. Any woman who lives the taste of her own pussy on my mouth is a keeper.
6. Getting rimmed.
7. Thick, meaty, protruding pussy lips. If they don't look like an overloaded ham sandwich or roast beef sandwich turned sideways, they're too small.
8. Women who are vocal in bed, meaning not only talkative or instructive, but also loud, moaners, screamers, etc.
9. Petite or slender or svelte or just plain skinny women.
10. Older women, up to ten to fifteen years older than I am. (I'm not going to reveal my age, but just suffice it to say that at least one of my children is an adult.)
Question, by your write-up, you seem to be referring to what turns you on so much that you can't keep from ejaculating even if you don't want to, but you asked what drives us wild, what drives us crazy. My list shows things that REALLY turn me on, but not necessarily things that cause me to explode the gooey glue. Have I answered according to what you're asking for?
