That’s pretty easily fixed actually, you just have to not do what you know makes you cum. Assuming that either rubbing or vibing your clit then you simply aren’t allowed to do that.
Your main alternatives tend to be penetration only, so your clit is out of bound and you can only fuck yourself desperately remembering how good touching your clit and cumming felt.
Or if that makes you cum too, you can try humping only, or go to anal only.
Try different things, see what works for you. You’ll be regretting it and a drippy needy mess before you know it!
