It's a muscle. Why do people go to gyms to work out muscles to make them stronger, but think this muscle gets weaker with normal work outs? Makes zero sense. Muscles don't get looser with use. Childbirth doesn't make it looser. How tf is a penis going to?
Honestly it doesn't make any sense. Someone's beloved and faithful wife could easily have more sex (with one man) than a single woman with lots of different partners. >

They only get loose from different partners. If they have sex with the same man, it doesn’t count. In fact, they might even get tighter over time. 
I am a man so I know what I’m talking about.
