Alright so my girlfriend and I have had sexy many times the past month when we first started to. Most times its been pretty normal and no surprises but once or twice, I noticed that she produces like a white substance that I can see very well on the condom. Also when this happened, it began to really smell (that fishy smell) a lot more than normal. Like I said this hasnt happened all the time and I havnt yet asked her what it is. Shes 22 and has admitted to a lot of partners.
