Ok, I have a huge fear of pregnancy. As of now I'm living with my dad, and this morning when I was taking a shower I noticed a white clump by the drain, my immediate thought was sperm. Like what if my dad ... yeah disgusting. But anyways, pregnancy thoughts are filling my head because I'm like what if he touched the soap, towels, shower curtain .. with his sperm, I hate this fear but it eats me, I've tried telling myself its not possible but in the back of my mind I have what ifs. Help -_-
