Aroused question???

This is a very weird question but it's bothering me something terrible. Here goes. So when I get horny/wet/aroused I feel like a cramping sensation near my clit/vagina. It's not a burning sensation and it's not really a hurting sensation either, it literally feels like a cramp. Especially when you get that warm, juicy feeling that makes you do a kegal. Also it doesn't happen every time I get aroused, just occasionally. Has anyone else experienced this or is this not normal? Thanks in advance to any insight or answers!
