For some reason, Vegeta seems to be very sexy as a male, but I also get the impression that he is likely to have sex in a self-centered way.
He seems to be polite in the beginning, but I think he will perform the routine of resetting the stress of his training by having sex with Bulma.
It is a selfish fantasy,
Yamcha seems to be very naughty lol, and I have the impression that he is good at using words and rushing things. He seems to be a typical playboy who is unfaithful, though he also seems to be careful to please women by preparing small gifts. That's just my impression lol.
