We're too Young for Sex Problems

My partner and I have been together for almost four years. I'm 21. She’s 23. As you can guess, we've been through A LOT together. We love each other to death; I can't imagine my life without her. I want her to be the one I grow old with, that I experience new things with, I want to have my children with, everything. But, there is a huge problem! Our sex life is down the drain and I don't know what to do anymore. It's basically the thing we fight about most often and that we're in a fight about right now!

The problem is that she wants to have sex all the time and I don't. There are many reasons for this, which when I tell her, she just sees them as "excuses, because you don't find me attractive anymore.” I work two jobs AND go to school, so by the time I get home at 9 pm, I'm exhausted, and I always have homework, so sex is usually the last thing on my mind.

When we were first together, sex was three times a week, now it's three times a month!

I'm bored in the bedroom

Besides me being exhausted, I'm bored. I've told her exactly what to do, where, when how, etc & she doesn't do it! I don't have the time or money to see a counselor. I want both of us to be happy, but I just don't know what to do! Please any advice would be extremely helpful!
