Significant other trouble..

I read my Bible today for the first time in over a year. Me and my boyfriend love together and we have a son. We are very sexually active. Tonight after I got done reading he says "well I was gonna try and be intimate with you, then I saw you and now I cant." He said he wouldn't feel right.. my question is how am I supposed to do this when I risk losing him? Should I read earlier in the day when he's not home? Is he being odd about it? Or am i? I mean we live together it's not exactly praised in the Bible either so why is one bothering him more then the other?
