I sympathise with you and your problem.
it does not make you feel wanted does it? more like used !
Sexual intercourse is designed to bring pleasure to both people , not just one.
If you know when he is going to want it, can you stimulate yourself first, so that you are already well aroused, even close to having your climax, then when he enters you and your sexual responses are active cos you are very close to your orgasm, would that be a turn on for him , and arouse some desire to please you in future?
and presumably if he just satisfies himself again and leaves you unfullfilled, you could finish yourself off privately , if that is your desire to do that.
