Your beliefs are your beliefs. But putting too much of an emphasis on sex as some spiritual or metaphysical, transcendent thing is a really good way to set yourself up for disappointment. Believe me, the first time is usually not described by anyone as spiritual or transcendent, if they are totally honest, lol.

Sex is purely a biological function. Vaginas are just as clean or dirty as penises...it kind of depends on the person they are attached to. I'm an RN; not to be crude, but in 15 years of healthcare work, I've seen thousands of both. They truly are just another body part. It's societal conditioning which makes us believe they are "dirty" and "gross." I mean, our mouths are dirtier. Fun fact.
