Swallowing semen puts me right to sleep. It's one of the only things that helps my insomnia. I was curious if there was a scientific explanation, so I googled.
I was surprised to find others with similar experiences and strayed across another interesting article touting the "10 Surprising Health Benefits of Semen."

Anyone else get sleepy after swallowing? Any guys have SOs who experience this? It's fine at night, but can be difficult after a midday tryst! Some woman claim to build up a resistance if they give enough blow jobs.
