Please don't listen to anything this guy just said.Good work man, the game is looking great.
etc.
1. No, just because a woman has had sex before it doesn't mean she'll cheat. That's just stupid.
2. There are plenty of good reasons a woman would use a dildo instead of having sex. It's not a waste of anything. And masturbation is not sex regardless of what implements are used to do it.
3. It's not a binary choice between sweet, pure virgin and mega slut. Normal people have a normal amount of sex with a normal amount of partners throughout their lives AND, a lot of them manage to stay faithful to whomever their current partner is while they are in a committed relationship.
He is right that vaginas don't get loose, really. Not through sex, anyway. That's a myth.
