I recently went on holiday to Spain to attend a music festival with a group of people that I met on reddit. I ended up spending most of my time with a tall, handsome expatriate who was very proper and exuded your typical British reserve. We smoked and watched a variety of bands together, and as the evening progressed, so did our subtle attempts at flirting. By the end of the night, we found an excuse to separate from our group for a few minutes and ended up making out like teenagers.
Over the next day or two, we discussed sex and discovered that many of our preferences and fetishes aligned. We are both bisexual, for one. After talking about that for a bit, he told me that he loves anal, especially from women. I was very turned on by that because one of my biggest unexplored fantasies was anal sex with a bisexual man.
