What are the differences between sun protection products?

I find choosing among all of the available sunscreens and sunblocks to be very confusing. Of the following three products I am currently using, which one is giving my skin the most protection: sunscreen SPF 30 with UVA, UVB, and IR sun protection; sunblock SPF 17 with UVA, UVB, and IR sun protection; or, sunblock SPF 50 with UVA and UVB sun protection? By the way, what is the difference between a sunSCREEN and a sunBLOCK?


What are the risks of gel and shellac nail manicures?

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?


Is it dangerous to have sex with animals?

1) I recently had intercourse with a sheep at a friend's house. He is a sheeprancher and one day he was talking about how good it was. He left town for a few days and asked me to feed his animals. I took the chance and gave it a try. The strange thing is that I enjoyed it more than having sex with my girlfriend. When I was a young lad I was molested by a female babysitter. I was wondering if you may think that the earlier incident in my life has affected my sexuality. I liked it so much that I want to do it again, but I am worried that I may contract a STD from the ewe. I have heard that you can.

Could you please help me?

2) I have read about men and women having sex with animals, e.g., dogs (Women on Top by Nancy Friday, Simon & Schuster, 1991). Apart from it being against the law (I think), are there medical reasons why this is not a good idea? For example, are there STDs that can be passed from animals to humans? Are there immunological consequences from depositing sperm into the vagina of another species? Is this kind of sex common?


Should I confront my partner about how he gave me herpes?

The man I have been seeing for six months, and with whom I have fallen in love, has transmitted genital herpes to me; I was diagnosed only yesterday with a primary outbreak — very painful, indeed. There were times when it seemed he avoided/did not want intimacy, which was often puzzling, because he was usually very interested; however, now I suspect it was because he feared infecting me. That I now know he has herpes seems to explain a lot of the "distancing" behavior, but I wish he had been open and honest with me. I have not told him yet, and my feelings are in a state of turmoil. What is the best way to approach this? I really have feelings for him, and I know he has strong feelings for me.


Should I start PrEP?

If my husband takes antivirals or post-exposure prophylaxis can we still have sex with a condom and still complete the process like normal? It is affecting our sex life because he does not want to infect me. I don't want to be infected but I knew what I was getting into from the start. I might start PrEP as it is now available to me. What are your thoughts?
