A lot of western religions are very negative about sex, but I'm pretty negative about a lot of western religions.
Non-religious people generally think that sex is a normal healthy part of being human. It causes certain pleasurable brain chemicals to be released, and in cases of ongoing relationships, the mutual pleasure is very important in reinforcing the pair bond. It is good for your emotional, mental and physical health.
Non-religious people generally think sex is fine, or even very good, provided that everyone involved is a consenting competent adult. There is nothing at all immoral about two (or more
) people doing something they like together.
In a lot of cases, people (especially males) with mental illnesses experience low or zero sexual urges. It just doesn't come up (hehehe). So, JB, if you're not feeling the urge, don't worry. Carry on with life.
Seriously, do some painting. Make model airplanes. if you can, go play with a puppy.
