I think the fantasy is far different to the reality of pregnancy risk. But my ex-fiance was very, very promiscuous and hardly ever used condoms even though she'd promise to and wasn't on the pill. So, I found myself having to using condoms with her, just so i'd know if or when she fell pregnant, it was unlikely to be mine. But in saying that, the excitement every month waiting to see if she got her period would drive me wild. I also knew in the back of my mind, that if she was to fall pregnant, there was a high likely hood I was going to accept the outcome and go along with her having it and raising it. In hindsight, I realise I dodged a massive bullet, but this 'fetish' and the excessive fantasising/ masturbation that goes with it can over rule a lot of logical thinking once it draws you in.
