These positions involve anal penetration: Doggy style penetration maximizes the depth of penetration, but can pose the risk of pushing against the sigmoid colon. If the receiving partner is male, this increases the chances of stimulating the prostate. The penetrating partner controls the thrusting rhythm. A variation is the leapfrog position, in which the receiving partner angles their torso downward.
I dont know how it happened. I started off watching lesbian porn maily girls squirting then went on to watching enema, then farting, then i discovered scat porn and got hooked. I've been exposed to porn from a young age about 5 and have watched it ever since. I'm not interested in girls at all, neither am I interested in personally getting involved in any kind of scat activities. But when I watch male scat it turns me on so much and I don't know why - I can't stop!
