Attraction is a natural and normal thing, it’s instinct. Him getting an erection at a movie is normal. Not to invalidate your feelings, because I know that if I noticed an erection during a movie I would also feel insecure and jealous. It’s just kind of a mental note to make that it’s unfair to hold him to a standard that is unrealistic. I have founds lots of men attractive and that’s normal, I jsut don’t get an erection to prove it.
