Through "extensive research",(lol) I've found that sometimes women just aren't in the mood..Not a big deal,as it's been said in here that once the drive cums back..Happy Days Are Here Again!!.If she is complaining though,then maybe look at the approach..A nice dinner out alone together does wonders..In the past,and I'll be really honest about this,I was just moving too fast,and she wasn't getting what she needed,so I needed to slow down,learn to use massage oils,and things like that to enhance the mood for her,too..Actually found out that doing things like that,made it more pleasureable for me,too.
A womans g-spot is about 1 1/2 inches in,so unless your smaller than that,you shouldn't worry..Making it love making session instead of a fuck,made a difference..Can't keep that puppy in there for an hour and a half,but you can make HER cum that long with the right research,lol..
Be more secure in yourself too..If you know that you did all you could to make it better for you both,then,it's time to talk about it,and see where things can be done differently..
