I was wondering if someone touched a surface that had traces of DRIED semen on it, would the semen transfer onto the person's hand? I have been wondering this because i seem to be bothered by it and feel i may become ocd.
Have you ever seen an episode of CSI? Usually material can be transferred from one surface to another. Factors will influence the ease of and amount transferred.
I think it wouldn't hurt to talk to your doctor or a psychotherapist.
