Wondering if there are any negative effects to masturbation while being sick. I hear it could be a cause of lower immunity levels, is that true?

For a number of years I have had acne from waist down. I can't find any information on it except for acne of the face and back. I'm embarrassed to wear shorts in the summer. Any suggestions?

1) Over the span of the last couple of years, I have noticed a significant number of moles appearing on my body. They have been appearing everywhere from my neck to my inner thighs. I had one on my neck since childhood, but now have so many more. Is this normal? Is it something I should be concerned with? And does child bearing have any relevance to this happening?

2) I have a mole which has turned very dark purple, and grown a bit in size (still small). This is the second time it has done this — last time was a couple of weeks ago, and it slowly faded back to almost nothing until today. Should I be very concerned about this?

I get cold sores around my mouth and nose all the time; I have since I can remember. I know that they can be caused by both physical illness and mental stress. Is there any way to reduce the frequency with which I get them, i.e., diet? Please help me, I feel like a leper.

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?
