FUCK!!!!!

So towards the end of me and my bf having sex my vagina was hella wet and gushy. My bf started to slow down and stroke my vagina really slow and he was kind of moaning. Does this mean he came inside me? He was back shotting me tho... does the position matter? Oh and we didnt use a condom. I knew i should have stuck to using fucking condoms -__- smh but could this possibly mean i could be prego?
