<human>: Summarize the given text in a few sentences.

My boyfriend and I were friends for five years, have been dating for over two years (the first year of which was an LDR), and living together for a year.  We are very committed and monogamous, though neither of us has much interest in "making it legal."  In general, our relationship is great, and I love him very much.

Over the past several months, I noticed that my boyfriend never initiates sex.  Ever.  We'd been having sex every day since we moved in together, and he seems to enjoy it and care about my needs.  After months of being the only one to initiate sex, I backed off a little.  On days I don't initiate, we don't have any sexual contact.  I still initiate about every other day, because I don't want either of us to be deprived.

Finally, I confronted him about it, and he said he just didn't have much of a sex drive, was working a lot, etc.  I was a bit skeptical, seeing as he has masturbated to internet porn and nude photographs of girls every single day since we've been living together.  I work the graveyard shift, so he usually does this when I go to work, which (if we've had sex that day) is AFTER we've had sex, if that matters.

I know that masturbating to internet porn is perfectly normal, and I have no problems with it usually, but it seems a bit excessive, and I worry that he's begun preferring it to sex with me.  He is MUCH more sexually experienced than I, but won't give me any feedback as to how our sex life could be better for him, and insists he isn't getting bored.  I feel really undesirable and unwanted, but I wonder if I'm over-reacting.  I don't know if I can ask him to masturbate less without coming off as an OAG...but honestly, if I never initiated sex again, we'd have a sexless relationship, and I fear he'd be perfectly happy whacking off to porn instead.
<bot>: My boyfriend seems to have lost interest in me sexually and chalks it up to being too tired to have a sex drive...then masturbates to internet porn.
