To masturbate, imagination is needed. When he is masturbating
he is having imaginary sex.
Instead of masturbating he should be banging you, at least every

You say you keep yourself, very clean. That sometimes work

sexually attractive.
On his part he is horny, no doubt about that. But he need to
bother you. To ask you to engage in sex. Annoying you should be a
secondary concern.
Previously, it has been one thing that leads to
another, and end in sexual intercourse. There is petting, kissing,
and rubbing, erection, arousal, and then penetration. This is
slowly truncated to, "Want to ____x-x_____?" (whatever is your
pet word for sexual intercourse), and as laziness sets in, he don't
want to bother anymore. The more he masturbates the less sex he
performs. Actually each masturbation should be one round of
sex.
The thing is now to spice things up, experiment with more sexual
activities whatever, it is now ok between consenting adults
within the privacy of you own home, and see what he like. Has he
perform cunnilingus on you? Its addictive to some men simply

extremely arousing. Maybe he likes a blow job, but don't let
him ejaculate, tell him he must do the conventional way.
He must want to ____x-x___ with you. You have to
find out what he finds irresistable
