Help what’s wrong?!

So, during the day I always feel like I need to see, but whenever I go to see only a little comes out and it hurts a lot but I feel like I need to push? Not like push push but almost like tense and then it feels better, does anyone know what it could be? I also had sex about a week ago now and this started happening about 2 days afterwards. Do you think that they could be related? I’m also wondering if I could have a cut down there and it’s sore from weeing on the cut (sorry TMI) ?
