A few years ago, I took a new girlfriend shooting one day at a public range, just a few pistols, her first experience with firearms. Next thing I know, she is practically raping me in the lane. I got blow job on the drive home, and we had sex for the first time (just inside the door) that night. I never considered the activity any sort of turn on, it is (was) just a hobby. Now I smile at target practice on occasion in remembrance.
So, on a date, have you ever partipated in an activity (not overtly sexual) with your date, that seemed to increase the sexual interest of either of you when there was no such spark previously?
