Someone asked about this only yesterday, if you scroll back a few posts you’ll see it. While the pill can have an effect, there’s a lot of other things that can affect it too. Do you use condoms? Is the irritation by sex a new thing?
Might be worth changing condom and/ lube brand potentially you are having a mild reaction to them or something?
Are you having 30+ mins of foreplay, focused on you? How’s things in your relationship? How’s things going with you and life in general?
The mental side of things is super important. Stress, illness, self confidence, sleep, medication etc also have an effect.
Also if sex has been uncomfortable for you, your body is going to tense up in expectation of that, and tensing your muscles makes sex more difficult and uncomfortable so it’s a bit of a vicious cycle.
