Me and my boyfriend were messing around and he put his dick near my labia and started rubbing back and forth and he started rubbing me with his fingers to get me more wet. He put it inside me and there was a lot of pressure and he started thrusting but it never went past his tip, and he constantly took it out. He told me he was about to cum, so he pulled out and pumped and then he came on the seat. I moved my body right away got in no contact with the sperm, put my clothes on right away and I am on my last day of my period. Should I be worried?
