Please do not shame sex! This is what the OP was talking about....being embarrassed & ashamed.
There's lot of ways to achieve orgasm besides sex too. Guess it depends on your definition of sex.

The OP is looking to us! WOMEN! For help. So help & guide her along this beautiful path of sexual exploration IF she wants it. Yes women are biologically built for reproduction. Notice men don't have a uterus. We were given that responsibility. The way we are built should be celebrated not condemned.
I'm sure there's plenty out there to read like on the internet that says how "bad men are & how bad sex is..."
But if you really research women sexually we're in the forms of many higher gods. Valued for our power & reproductive ability!

We are powerful!
Please don't forget that.
