I was dating a girl who teased me about how much of an ass guy I was and she was shocked I had never had anal sex before. So she just flipped up her skirt right there and said 'come on try it out'. So I dropped my pants and lube it up and went to town and she started fingering herself and we both came hard.

All my gfs beforehand flipped out at me when the topic came up. even my kinky ones were anti-anal.
