Dumb question

Sarah

So this is such a dumb question. But what can I do to help with a dry/ burning feeling after sex? It doesn’t happen every time my so and I do it and when it does happen it’s after we’ve been doing stuff (foreplay and sex) for 30+ minutes) I pee sometimes before and most of the time after but I don’t get UTI’s. It’s like down there is just irritated with all the friction almost. (I’m almost 21 and engaged getting married in 17 months)
