Why do my bowel movements change when I get my period?

1) I've suffered weird digestive things when I have my period. The way I have heard it explained in my MCAT class is that the same hormone that causes the smooth muscle of the uterus to contract unfortunately works on all of our digestive organs as well, particularly the large intestine. So that's how I've come to grips with the apparent confusion of the digestive processes during my period.

2) Does a person's menstrual cycle regulate her bowels in any way? I have had some problems. The week before I get my period, I have loose bowels and the week afterwards I am quite constipated. Is this normal? Is there anything I can do?


What to do when my boyfriend cares more if I cum than I do?

It's very hard for me to orgasm during sex, even if I help myself. I can do it all by my lonesome very quickly, but as soon as I'm with a guy, I just can't cum. However, I'm not worried by this whatsoever. I love sex, and I love everything about it. I love the act of sex, I love pleasuring my partner, I love the sights, smells, and sounds of sex. If I don't cum, meh, I'm still very happy. I'm no happier if I do orgasm during sex.

My problem seems to be keeping my partners happy with my contentment with not orgasming. They seem to think it's their life mission to make me orgasm. I had one boyfriend with whom I actually faked orgasming for a good two years because he was so upset that he couldn't make me cum. Every other partner I've had since then has taken it personally that I can't orgasm with them. It seems to put a bit of strain on my relationships.

I am with a new guy that I care for very deeply. He has been very understanding of my not orgasming, but he seems to try that much harder, and I think he is getting frustrated. I have orgasmed once since we've been together (a mere month and a bit), so it can be done, but I really don't want him to take it personally. I've told him already about this, and he said he was surprised that I'm cool with it. I REALLY don't want him to be disappointed and have this strain our relationship (like every other relationship I've had). I really do like him that much.

What can I do or say to ease his mind?
