No it is probably urine, white is semen. However, dried semen may be off-white.
No. Men can have white stains or yellow stains on the front of their shorts. Some men can get easily aroused (for example: seeing a stripper) and perhaps have semen stains, but it doesn't mean he cheated. Usually the yellow stains are from urine or discharge. Marcy
