Don't get me wrong I'm not a prude but I just find it odd for example when a friend says to me I gave my dh a bj whilst he was driving.
I find it odd as she said it like it was a big taboo and ooh wasn't she so fun and naughty for doing that.
I really don't know if I am explaining myself right, but to me yes sex is great but it's a natural thing and a huge majority of the world does it. So I just don't get why some people 'show off' about it.
