What can you do make her feel comfortable? Make her relax, safe, softly and slowly. She suggest him to lie down beside her and do the foreplay to relax her. While she is asking for more then only go down to her and rub her clitoris. After this then only penetrate, the penetration will take her to climax if everything is going well. When she is near to climax, she may need a catalyst to take her to climax. The sex shrink suggest that you may for instance try to grab her ass as there are a lot of nerves that may make her climax.
I have sex a lot, and often but I only know it's so complicated right until now. Or maybe I should say there are so many procedures for sex. And this may not be my girl friend's preference, so much to learn, luckily we have internet online to learn all these stuff.
