I've never done dirty talk with a lady. Outside of the hobby, I've only really had the good girls, and none were freaks in the sack. That shit gets old quick! LOL I think a dirty-talk session would be hot as hell! It would be a fun change of pace.
On a side note, I asked Siri on my iPhone 4S to talk dirty to me. She replied, "The carpet needs vaccuming." Then she replied, "Humus. Compost. Pumice. Silt. Gravel." :/ I guess there are somethings only a real woman can fulfill... LOL
Give it a shot if you have the new iPhone. It made me laugh when I first tried it.
