I’m sorry to hear that. Firstly, talk to your doctor. There are a considerable number of different pills (and many more contraceptive options) which can have very different effects, so I suggest you get to see them ASAP and just be frank with them and you can try something else.
You’ve written to a denial blog so I’m of course going to recommend you try some edging and denial to get your sex drive up. Make sure your partner is focusing on different ways to stimulate you, some new toys might help, and he could practise his oral skills! But, with the intention that you don’t cum, maybe you’re allowed one every three days… maybe that works so well you drop back to even less! Better horny and denied than not horny at all, right?
But yes, first, go talk to your doc, they will actually know what they are talking about!
