9-10 would be ideal. Yeah, you limit your choices with some partners, but you can probably fit most of it (if not all of it with some people) in your partner and have them enjoy it while still having a lot of fun yourself. Not to mention the WOW factor of the size, not just during sex, but in casual settings too. Also... I think I’d want to be a grower. Cause even if you’re a grower, you’d still have to be pretty big when you’re soft. It’d be priceless to watch people’s reaction as something already big just keeps growing!
