Mathias, sex with a woman is kinda cool because the vagina lubes itself up.  If you finger her the general rule is to use only one finger (the muscles tighten to fit around whatever goes inside, that's why tampons stay in), don't go shoving 2-3 in all at once.  Move your finger up like a "come here" movement against the top, it feels weird when you do it sideways or backwards or just poke aimlessly.  If there is more than a 6 inch height difference, missionary position can be uncomfortable and weird.  I'm sure she knows what she's doing though, let her lead.
				
			 
	 
	 
 
		 
 
		 
 
		 
 
		 
 
		 
 
		 Onder, we've all been there man. I know how you feel. I'm a tits guy myself, but a Grade A ass can also drive me into an absolutely primal frenzy.
