Who knows? Jesus said some stuff on the topic, so did God. It's probably a matter of the heart.
Jesus said if you look at a woman lustfully then that's just as bad as having sex, which is impure and stuff. God wants his people to be pure, and Jesus helps purify them after he saves them.
It's hard to say that's the truth though when so many people claim Jesus power and then have promiscuous sex, but eh, it doesn't make him any less real in my life.
good day and good luck with your sex endeavors. haha
