Do you know anything about the safety of eyelash extensions?

My girlfriend and I were wondering about dying her pubic hair. Is it okay to use regular hair dye or are there special products to use for it?

I have a question about mumps: I had mumps while I was thirteen-years-old. I remembered that because of embarrassment. I was afraid to tell my parents about the inflammation (swelling of the testicles) at the same time I had mumps. I did not have treatment for the swelling of my testicles due to mumps. Later, the swelling went away about the same time as my mumps. Although I still can produce semen, I am deeply disturbed whether that swelling could have hindered my fertility (i.e., no production of sperm due to the blockage of the sperm channels).

I’m having a burning sensation when I urinate and it still burns after I urinate. Also, I can’t urinate all the way and am continually having to go to the bathroom. I was diagnosed with kidney reflux when I was a child — could this be that?

I love getting my nails done with a gel or shellac manicure. The polish doesn't chip at all and stays shiny for weeks. I'm just worried about the UV light used to seal the manicure - it is almost like a mini tanning bed for your hands. What are the risks? And are there any bad chemicals in the polish?

I was having a conversation with my roommates about pop and coffee and we were wondering which is worse for your teeth, the pop or the coffee? And what do they do to your teeth when you drink them?

For the last year or so, I haven't been able to cry anymore. And when I do, absolutely no tears come out. My eyes just water up, but there are no tears. Is this normal? Should I be worried?

I am curious to know whether there is any right and wrong ways to wipe one's ass! Is wiping sufficient or should it be cleaned with water thereafter? I've heard that people use water to clean, which is regarded as more hygienic in foreign countries.

How safe is wearing a thong in terms of hygiene after a bowel movement? I wonder because a thong literally sits right on the anus. Are there any products available commercially for genital hygiene?
