It could be an excuse as some have suggested, however, let's go a little deeper (pun intended
).
Okay, what we are talking about here is a lack of enthusiasm. It is not her fault and this is just something that you both need understand and then work hard to find a common solution.
Lack of enthusiasm is no reflection on your dick size at all. It is very likely a reflection of her past mixed with your (both of you) love making techniques. Simply state, she is not turned on nearly enough and her vagina has not gone through the proper changes required for optimal penetration.
What do you do to fix this? Well, with most women of this sort you will need to take the lead to find the solution. So now we know that you are in the lead but you are listening and watching intently for signs, both positive and negative. These signs will guide your path.
Leading the way is hard and requires lots of patience but pays off big in the end. Simply stated, if you transform a woman that "appears to not like sex" into a woman that is into it, she will look at you as her king.
How do you do it? Well for starters, talk to her. Ask her waht really turns her on. If she will not talk frankly to you then go ahead and tell her what turns you on and then proceed to ask her to help turn you on with these new ideas. This will loosen her up (pun intended
) and eventually she will either show you are tell you what she wants.
Go slow. Women are like fine wine and they take time to get just right and ready for the act. The idea is that you work with her until she is very horny and wants it. Mind you, this might mean talking to her for hours or even days to get her in the mood. It might mean talking dirty, role playing, fingering, pussy stretching, spanking, licking, toys, �naked people movies� or about 1000 other ideas. Find her trigger and then work the fuck out of it (pun intended
).
