Here is how it works

Because men can continue to secrete small amounts of semen for up to 2 hours or more after each ejaculation or sexual encounter, traces of dried semen will almost always be present in their undergarments after sex.

Even if a man uses a condom during sexual intercourse or even if he only had oral sex performed on himself, there will still be traces of semen in his underwear. As long as the article to be tested has not been washed, traces of dried semen will remain present for very long periods of time, so any item that you think may have been stained as the result of recent sexual activity can quickly and easily be tested with GranburyPI/Checkmate.

For women, the most import factors to consider when using this product are the size and location of the stain in the underwear itself, as well as the circumstances surrounding the suspected semen stain. 

Say for example you discover one small localized stain at the bottom of the underwear. This may indicate dripping after masturbation. But, if you happen to find a stain in the upper waist band area of the underwear, this would more than likely indicate he was at least semi erect, and may have pulled his pants back up quickly after ejaculating. 

Semen stains in the waistband area of the undergarment are usually accompanied by several other semen stains that were deposited  in various locations as the erection subsided, as well as a fairly large stain at the bottom.

He brings the evidence home to you and doesn't even know it This is really, really simple... Say for example, he left the house on Sunday afternoon, and told you he was going to play golf. Then, when he came home and took a shower, you got his underwear and did the test. If any semen was present, what is he going to say? I was masturbating on the golf course ? A woman's intuition combined with this easy to use home test kit make for one complete investigation. Remember. You're not always looking for a positive test result.
