How can having multiple sex partners be a risk factor for cervical cancer? What is the difference between having sex with one man one thousand times and sex with one thousand men (not that I'm planning to!) one time?

For about two months now my whole body had been itchy and will sometimes break out into a rash. I tried switching soaps and laundry detergent; I just don't know what it is. It's on my arms, legs, back, inner thighs, feet, etc. I'm scared and really want to find out what's wrong and stop itching.

1) I tried looking for an answer to my question in the archives, but didn't find one. What I want to know is if it is normal that my boyfriend's semen has clumps (I don't know how else to describe it) in it? The semen has never been clumpy before, but the last time I gave him a blowjob, the semen had a chunky consistency to it. Should I be worried that this may be an STD, or is this kind of thing related to other things, and if so, what are they? Thanks.

2) I just realized a few days ago that my sperm comes out in pieces. For example, they are as thick as small boiled rice pieces... is there a concern to worry?

My girlfriends and I are debating something: Are baths bad for the vagina?

Please help! My skin is drying out like you would never believe. It is scaly and itchy at times. Could this be as a result of the weather? Are there any pointers that you could give me so that I don't feel like my face is cracking and looking like garbage? It seems to get worse after I shower. What is this? What can I do?

I was hoping you could answer a question for me about birth control pills. There is a history of breast cancer in my family (my mother). Is it true that because of this, it is unsafe for me to use birth control pills? A few friends have recently had condoms break during sex, and I am looking for a type of "backup" contraception system.
