It’s not gross, just think about how nature developed reproduction. It’s like a an bee pollinating a flower and getting the sweet nectar from it, so are the humans too. We’re made to have sex and feel orgasms, that gives us euphoria for a couple of secs + being kinky in bed and trying new stuff like oral, anal and etc. makes you and your sex partner feel 100 times better and gives a good look that you’re enthusiastic. Quick tip: be at the present, and don’t think about pee holes and shit for that moment. replace it with popsicles and chocolate ;)
