Semen Detection Kits: For the men who believe that there significant other may be cheating on them, and inside their own house, a semen detection kit can be purchased inexpensively. In theory, this kit will identify semen stains on sheets, clothing, and surfaces. If you really want to get scientific, there are labs that will compare two semen stains (providing you give them a sample) to determine if there is an outsider in your relationship.
