Hi everythime I want to have sex with my boyfriend he doesn't but then when he is in the mood we do it.
But sometimes I just want to have sex and he doesn't!
And he is shy too but I mean we have been together for 2 and half years he doesn't need to be shy with me anymore... how do I get him in the mood without going all out!

Communication is everything, talk to him. Tell him every time he wants to you try and accommodate his needs, so you would appreciate it if he would do the same. If he can't take your feelings into consideration, why are you still with him?

Maybe going all out is your ticket. Everyone responds to another's needs differently. Some guys clam-up with verbal requests and some don't. Has nothing to do with not loving you. One way to communicate our intimate needs would be non verbal. Talk with him about this. Let him know how you feel and ask him to work on solutions with you. In time you'll both be more comfortable and maybe he'll be able to jump on your bones at a moments notice. You hope... Best of luck you guys.
