Disinterested girlfriend

Sex is about so much more than the physical connection felt between (in this case) you and your girlfriend when having intercourse. A woman needs to feel that emotional connect with that special man in her life. She needs you to listen to her throughout the day. She wants you to ask probing questions and develop a strong emotional attachment that shows you really care. Additionally, she needs to know that you notice the small things that she does on a day to day basis...how does she look? how does her new fragrance smell? how awesome is it that she works out religiously while holding down a full-time job? how fantastic is it that she makes you laugh, or makes your bed, or cooks your dinner? She need to feel your interest and your desire and appreciation for her throughout the day...not just right before you're ready for a nice "roll in the hay". Pay close attention and give appreciation for the little things each day. Let your girlfriend know that you desire her all the time and truly want to know everything that makes her tick...not just what makes her tick sexually. You might just find that with some fine tweaking of your current existence in this relationship, that your girlfriend quickly converts to the sexual aggressor. Best of luck.

Try changing ways you make love....Be creative.....Watch some X rated films with her......

I agree with Elieva and couldn't have put together a better answer! Two thumbs up for a great answer!

I think you should show her your affection, devotion and appreciation of her in everything she does for you.  Being thoughtful, caring, loving, generous, patient will do the trick.  I think that these are the things that make a man lovable and no woman will take this for granted.  These, for me, is the best aphrodisiac.

You need to talk to her... sometimes women and men dont see eye to eye and a lot of times the best way to find something out is to just ask. You both will feel so much better more comfortable and it will make your relationship stronger knowing exactly what each other wants. Also, I'm in a relationship myself and the longer your together the more the relationship changes and if your with the right person it will change or the better! A lot of times the way it works is the longer your with someone the less you have sex and its not because you are falling out of love or yous are bored with eachother it could be that you just don't "need" it as much. Everyday I wake up I fall more and more in love with my boyfriend ( we don't have sex everyday sometimes we dont have it every week) but everyday we are very affectionate towards eachother and it makes our sex life better and our relationship better. So maybe you should try spending a little more time laying with her kissing her head, or hold her hand, or one of my favorites is when we are in the kitchen making food my boyfriend grabs my hand and pulls me close to dance with him and he sneaks a kiss (it makes me have butterflies and that feeling inside that i couldnt be happier). I hope everything works out the best for you!
