When having sex, the muscles of the body tend to tense up. This tenseness can lead to cramps.
About 4 and 5 calories per minute so, but obviously it varies by how vigorous the sex is!
The Y chromosome is the male sex chromosome, but males also carry a X chromosome from their mother. XY. The female sex chromosome is the Y chromosome; YY is female. ( generally, as sex chromosome number in both sexes can vary )
It's NEVER safe to have unprotected sex. Use some form of contraception, risking it isn't worth it.

No; in some cases, such as HIV/AIDS, you may not even be aware you have the disease. That's why people should be tested if they have had unprotected sex (and even such protection as condoms is not 100 percent effective).
