I am a first-year student and I want to get my nose pierced. This isn't just a whim; I've wanted one for a long time. However, I know that there will come a time when the ring will look juvenile on me. My question: will such a hole close up fairly quickly, without leaving an ugly scar?

During sex, my husband likes to squeeze and suck my nipples. I enjoy this, but am worried that this type of pressure on the nipples may cause problems later on: we are planning on having a baby in a few years, and I want to breastfeed. Might the pressure of squeezing and sucking hurt my mammary glands and ducts, making it difficult or impossible for me to breastfeed?

As the summer is soon to arrive, I was wondering what type of clothing should I wear to protect myself from the sun? Also, what color works best, light or black? I seem to be getting conflicting answers on the Internet. I am a fair skinned male. Thanks for your help!

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?
