I was with a group of friends, one of whom loves to talk about sex a lot. She asked one of our more reserved friends what her boyfriend was like in the sack. I think the woman just likes making people feel uncomfortable. I think she feels she is cool.
But it’s such a stupid question because sex, probably more than most things, is subjective.
I think these people just like “audio porn” and get a thrill hearing about the ins and outs of other people’s sex lives.
