I've just been approached on OLD by a man looking to act out a fantasy of getting a woman pregnant. So shagging when she is most fertile and presumably having this whole fetish conversation about it - as he wants her to act out being desperate for a baby. He describes this as a delectable fantasy.
I should take him up on his offer and act out the uninspiring, functional, somewhat begrudging timetabled sex that you end up having when you actually are TTC in RL. 😐
