<human>: Can you condense the text into a few key points?

I know that people don't become blind when they date and that it's natural for him to still find other people attractive. But that mixed with the fact that we don't have very much of a sex life (he has a 'low' libido but I'm pretty sure he masturbates frequently) has got me feeling really down. 

He made a comment about someone on reddit today and I got a little upset and tried to explain that I didn't like that. I also asked him how he would feel if I said something like that and he said he wouldn't care but that "maybe [he's] just jaded."

Am I overreacting? Should I try to be less sensitive? I just think it's rude and considering that he doesn't really make a point to ever tell me that he finds me attractive, it really gets to me.
<bot>: SO makes comments about how attractive other women are. It gets me down because he doesn't really show me that kind of attention... I don't know what to do.
