Yes. I think it's super hot for a dude to be locked and unable to jerk off. Especially when he's sucking my dick and getting me off. Milking him once a week and seeing the frustration in his eyes as his balls empty out without orgasm. And in this state of constant arousal he's pretty much always ready to take my dick.I take it this is from personal experience?
Chastity is growing popular among women in hetero relationships as well. It's the same thing. He craves pussy all day every day. She gets what she wants and his only source of sexual pleasure is pleasing her.
