Is it true that I’m being unrealistic about my sexual expectations?

Nope, just have a high sex drive. I was with a woman like that for a while. She generally wanted to have sex 3-4 times a day. A day! (For the dumbasses, she was perfectly healthy, had never been sexually abused, she just had a very high libido. Those women do in fact exist and are more common than you’d think.)

That’s just…not me. I literally physiologically cannot do that, and couldn’t even when I was 18. If that is important to you, find a partner who is the same.
