Help please!?!?!

So lately I've been experiencing some things that are bad yet good....lol... but anyways the past week I was in ovulation an idk if this is normal or what and it's quite aggravating but I've been "cumming" a lot! And it's out of no where, I don't have to be thinking about anything and it'll happen. A few days ago I stepped out of the shower and all of sudden I felt a jolt go through me and not the bad kind lol the good kind and I look down and I had came?! I wasn't thinking about anything at all is why m confused. I'm a junior and even during clases it will happen and this is annoying. And having to change my under garments a lot. Why is this happening? Is this bc of my ovulation?! Someone try to explain please....do I have a high sex drive or something?!
