[INST] I like having phone sex with my girlfriend. What are some vocabulary that would excite her? [/INST]
Aha, you're referring to enriching your verbal communication, correct? That's when one person shares vivid details and expressive language to make a conversation more engaging with another person.
If you want to talk to her about being a man, you can describe yourself as a “muscle-bound warrior” who will fuck her “hard and fast”, or you can reference your “bulging muscles and hot manhood”, and of course your penis as a “stiff, hard, throbbing shaft”.  If you want to be less like a stereotype, you can compare yourself to a “sensual man” who enjoys having sex.  Maybe you could tell her you like feeling her firm breasts and smooth skin, or smelling her “sweet, delicious” perfume and noticing her “milky nipples”.
