I need help. I don't know what's happening down below.

Please bare with me as I don't exactly know how to explain it and if it's the right term for how I'm feeling down there. 
For less than a week, there has been a weird pressure down below. At first, when I went to pee, the pressure ached a little that it hurt but it wasn't as painful, just slightly there. And it felt as if I needed to orgasm or I'm horny, but I don't know if it's that exact feeling down there. (So sorry if I'm confusing you all :( ), At first there was a little discharge when I wiped (like slimy substance when I wiped and clear discharge) but it was only cause I've been having a lot of sex that passed week beforehand. And there's still pressure down below but no slimy discharge. 
Sorry if this doesn't help at all.
