I "found God" in my early 20's and decided to remain celibant until marriage. Worst 5 years of my life and I ended my celibacy with someone I had just met. Sex was readily available but like you, I thought sex and love should go together. I admit to also having guilt about sex, or sexual thoughts. Now I see it as repression and not very healthy. The odd thing about sex is that it sometimes evokes love in people that already have a relationship. That's what eventual happened to me. And as an artist, I see no shame in nudity, assuming it's in good taste. I've also used that as a pick up line so make sure everything is above board.
