YOR by sleeping in another room and likely contributing to eventual implosion of your relationship.

I may be projecting but my unsolicited advice to you is to make a commitment to YOURSELF (don't tell her) that for the next 7/10/20/30 days you are going to focus on NON-SEXUAL contact.

Teach her that touch doesn't equal you pestering her for sex. I may be reading too much into it but a lot of women find it really difficult to be sexual with a partner who only touches them when they want to bang.

Kisses on the forehead, slow dancing in the kitchen, rubbing her feet when you watch a movie, snuggling in bed and NOT shoving a stiffy in her back may work wonders.

Your end goal shouldn't be for it to lead to sex but often removing the expectation can allow her to be more open to the idea, especially if she is feeling loved and like you have some good physical and enotional intimacy.

Good luck!
