Because I'm a perv that likes young and old women. I personally wouldn't say younger is always better. If I get even a hint of being stuck up I stay away. Huge turn off. Also really don't like tattoos, piercings, bear claws, and nose rings on women for the most part. Tattoos are nice if they don't look like some billboard that been graffiti-ed on and more like a piece of art that actually complements their looks.
There's no such thing as risk free sex. I take a risk outside of sex every time I meet a new one in fact. It could be a scam, I could get robbed, or it could be a sting. I'm tired of playing it safe though and living an uneventful life. Who cares about living if you're just really existing and waiting for tomorrow only to do the same thing over and over again?
