Yeah just another point on the domination, as it is quite common with guys:

Just make sure you've found out exactly what's cool and what's not with the girl before hand. If you get carried away you can really scar a girl/bring flashbacks from the past and it's not nice. I've done it before with someone I cared about, didn't go far with it (no weird shit) but I hated myself for how I'd made her feel non the less.

Other than that I see absolutely nothing wrong with mild domination, most girls like a bit of hair pulled and arse slapped.
