You can also tell him you d like that and that you want him to use it on you
orgasms sometimes with his hand or tongue
Am sorry to be so straightforward, but does he gives you orgasms? I suggest you get yourself a vibrator, like a bullet for the clitoris. It's a small little toy (easy to hide). At least some of your frustrations will disappear
See what toys you can use together which can make you orgasm, there are also sleeves that men can put on their penises to create a bigger length and provide more pleasure for their partner.
