Step 1
Buy a semen detection kit online or instore, and read the directions carefully so you know how to use the kit and interpret the results.
-
Step 2
Find unwashed articles of your wife's clothing, preferably something you suspect she wore while she may have been cheating. Don't worry if the samples are old, most high quality semen detection kits can identify samples that are several months old.
If you have trouble getting a fresh sample because your cheating wife does laundry frequently, you should volunteer to do the laundry so that you can have access to semen stained underwear. -
Step 3
Test the underwear for traces of sperm. If there is even a little bit of semen, the kit will detect it, and you can be sure there was another man.
-
Step 4
What do you do if you don't find any semen but you know your wife is cheating? Keep in mind that the semen detection kit will only detect sperm if your wife's partner was not wearing a condom. If the affair partner wears a condom during sex, you won't find any traces of semem on your wife's clothes. In this case, you may want to try another cheating detective method.
