<human>: For the most part my relationship with my boyfriend is great. We have a beautiful little boy and I love and care about him very much. 

But, since we had our son two and a half years ago, my boyfriend has developed little or no interest in sex. He will have sex with me once a month maximum and only if I initiate it. Other than that he is perfectly content with us not having sex and laying in bed having a quick cuddle and a peck on the lips and going straight to sleep.  

I've brought up the issue several times. He blames it on being tired when he gets in from work or there being housework to do. Basically if there is dishes in the sink or any ironing to do he can't get in the mood. 

He looks at pictures of girls and saves them to his phone (people who are a lot slimmer, fitter than me. I'm a size 12) and I'm beginning to worry that because I know weigh more than I did in the past that he is no longer attracted to me and trying to sugar coat it. 

I don't feel as if my sex drive is a big enough issue for me to end the relationship as I feel like I'm ruining my son's chance at a happy family if I end it for that reason. 

Sorry this might be TMI but I've tried going to bed naked. No response. I've tried dressing up, nothing. I've tried literally everything I can think of.

Any ideas for bringing the spark back?
