First, semen anywhere helps a woman’s sex drive regardless if it’s left in a vagina, ass, or mouth. The mouth is probably the least effective being that the acids in the stomach can destroy the testosterone, while the vagina or colon would absorb much more effectively. The colon being the quickest and most effective. This is the reason why some quick-acting seizure medications are inserted rectally – the body absorbs chemicals the fastest through the colon walls, semen/testosterone included.
Below I will piece together a few articles and let the reader decide. As far as I know, this claim has not been proven and it originally started when my wife, Nessa, started to leave my sperm in her ass after sex. For whatever reason, it seemed a bit cleaner to pull out in the last few seconds and put my head in her ass and unload. She liked it, I thought it was a bit more kinky, and her vagina always stayed fresh to eat, not that my sperm has ever scared me away. However, it definitely was much fresher (no day old sperm). If her ass wasn’t as fresh, well… it’s her ass.
We immediately noticed that her sex drive shot through the roof. She began wanting to deepthroat me. In fact, this sparked her entire need to deepthroat (see “Deepthroating – My Introduction”). She went from initiating sex 10% of the time to 75% of the time, and she demanded that I cum inside her, especially in her ass.
Unsure of exactly what was happening, whether it was her maturing sexually, her age, or the semen in her ass, I began to experiment. For weeks at a time I would only cum in her mouth or vagina and slowly her sex drive would decline. She didn’t notice, but as a man, I did. If I came in her ass, within the next 15 minutes and lasting for the next 48 hours, it seemed to affect her libido. Her oral would change from slow and pleasant, to aggressive and demanding. Her sex talk would go from dirty to extremely dirty, especially when she talked about my cum.
First let’s talk about the contents of semen, specifically testosterone.
