My wife and I have been married 13 years. I've nearly always been the one to initiate. Every time, she just rolls onto her back and waits for me to penetrate. She's not sexually adventurous at all. I try asking her what she likes or what she would like to try and she merely states that she doesn't know… that she's a simple person. The rare times that she does initiate, she'll get me real big and fired up by rubbing me, but then she'll go resume her usual position flat on her back. I'm constantly the one wanting to find new ways to please her and make her go wild. She doesn't seem at all curious to know what I like or what feels good to me. Other times, she'll spontaneously come up to me and rub me until I'm hard, making me think we're about to have some impromptu sex, but then she'll cease all activity like nothing ever happened. This leaves me feel like she's leading me on and is very frustrating. I've told her this. She occasionally likes when I use my finger or give her oral, but never asks for it… or for anything. It really seems like her idea of great sex is short and sweet. Essentially, she doesn't know what she likes, doesn't ask for sex, doesn't care what I like, doesn't seem enthusiastic about sex even when she initiates, and turns me on only to leave me hanging. What the heck do I do?
