Orgasms

I’ve been having these really weird orgasms lately from clitoral stimulation. Basically when I orgasm I have this massive urge to push really hard and it feels really good but this has never happened before and now it’s happened like the past 3 times I’ve orgasmed. I literally push so hard I feel like something is going to come out of me (and sometimes I fart lol) why does this happen and has anyone else experienced it?
