I have the exact same
fear/obsession. I am always thinking about how traces
of my semen may have leaked out
of me somehow onto my blankets at night and then somehow get on everything I own. I visualize it being everywhere, even though no one else can see it. It is completely destroying my life, I become depressed, and have also thought about suicide to end the pain of it. The few people I have told about this do not and cannot understand, but you do. Thank you for posting.
