So, my girlfriend and I have been together for over 5 years and just got engaged. I love her very much and am extremely attracted to her. There's just one problem... We only have sex when she wants it. Me being a 25 year old male, I seem to crave it a lot. I would like to have it once-a-day, but I understand that is a little too much to ask. So I try 2 or 3 times a week to get in her pants, and most attempts fail. So, we usually just do it once a week and it's when she's horny. When we do have sex, it is great for both of us, I make sure of that. So, we have had discussions about how I would like to be more sexually active and how I sometimes feel deprived or neglected, but I hold back because I don't want to appear shallow or pathetic and I really don't want her to feel like an "object" instead of my fiancé. So, my approach for the last year or so has been to just be happy to get it when I can, but then that brings up feelings of resentment towards her because I start to feel like she doesn't care about my needs. You also have to understand that I do anything and everything for this woman. She has a very laid-back and good life because of me. And she'll be the first to tell you, I am very clean-cut and handsome guy who treats her great. With all this said, I am starting to worry about us and I'm not sure if I can deal with this the rest of my life. Before I marry this girl, I needed some advice. Is this normal? Am I just being a horny creep? Is she being inconsiderate? Should I marry this girl?
<bot>: My fiancé denies me sex more often that I think is normal. I treat her great and feel unappreciated. Do I crave sex too much? Or is she being inconsiderate?
