you definitely have a point.....but I still doubt the main assertion that a man can't feel the difference if his woman was with another guy. It just makes sense......you get used to the way a pussy feels, it's fairly predictable if you're with a woman for some time. Now she goes out the night before and has sex with a monster, or uses some ridiculous dildo on herself.....she's just going to be looser than she was the previous times you've had sex. If I felt that, I would naturally ask her what she's been up to.
