Good question, i think they like every bit of it. Am sure if a guy offers them they would not reject the offer in most cases. Usually they are very high on oestrogen just like you have said. The hormones are raging out of control at that time and they ask for stuff that most people wouldn't do in most cases. If i can even go further, there are some men who are drawn towards pregnant women for sex than those who are not. According to the men that's when it is more enjoyable. I would go deeper with this but i don't think this is the right platform. Anyway i know there are women who cannot even stand the sight of their better halves when they are pregnant. This is not because they don't love their husbands but you can blame it on the pregnancy and the raging hormones. Sometimes i wonder why hormones would make one dislike their spouses that is something am yet to unfold and know the reason behind it. There are those who will expect their spouses to be there at all times. They will demand a lot of time from their men because that is what the body wants. In rare cases you will find women even begging for sex all the time, that's when the men start wishing they had a job outside town so that they can rest hahaha its funny but serious at the same time.
