HELP!

Lately my vagina has felt like its gotten tighter and I mean really tight. When I tried to have sex with my boyfriend he could barely get his dick in me even though I was super wet and turned on. so when he finally got in I felt pain as he entered and pain while he was thrusting. I felt some type of pressure in my stomach and ovaries. during the sex I had this while lotion like cream discharge come out of me and yes out of me. it wasn't his sperm because I can tell the difference. Has anyone had an experience like this or know what's going on??
