>>5174how? you can get zero orgasms even if you're psychologically enjoying having sex/masturbating with a basic dildo to fantasy/porn/whatever if you don't stimulate it right or your partner is a good person but terrible at sex.
comparatively, you can get a clitoral orgasm pretty quickly if you have a vibrator, someone else's or your fingers, etc because the clitoris is much more sensitive and is the only organ having zero purpose besides being stimulated during sex
exercise-induced orgasms also exist but they're caused by exercise (mainly cardio, weight training and abdominal-focusing (suggesting an area which can be physically stimulated during reps)) and it doesn't really sound like they'd be watching porn or even imagining sexual activity during them
