Understanding and Addressing Low Sexual Desire in Partners

Question
HI.  My girlfriend is a very shy quiet girl who isn't very sexual and doesn't enjoy sex.  I feel this is probably a phsychological thing just judging by her personality and she can get wet so physically everything is working.  I read somewhere that a girls PC muscles are important for an orgasm to happen and she doesnt seem to have any as ive asked her to try and tighten up to see if it makes a difference in how it feels but she can barely tighten at all.  I read somewhere that psychological problems can cause tension down there thus weakenign the muscles.  This all makes sense because she claims that her clit has been sensitive but hardly ever but inside her has never been sensitive.  So should all girls clits have the potential to be stimulated and is there any special way i should do it besides just rubbing it? if u can make any other sense of this it would be appreciated, thanx.

Answer

well each women is different when it comes to sex. i feel she is not ready and doesnt really know about what is to happen in general.

i feel the best thing here is,buy some books,read them together and take it from there. there are alot of books about sex out there;

good luck;
