<human>: So I've been dating my girlfriend for about three months now and I honestly have to say she's the most amazing girl I've ever met in life, she's absolutely beautiful and fits my life perfectly. 

I guess you'd say that this is my first real relationship, though I've had a lot of casual sex. So there has been somewhat of a learning curve to being in a relationship, but I've been honestly trying very hard to be a good boyfriend to her, she absolutely deserves it! She suffers from anxiety pretty severely and has had some bad things happen to her in the past but I'm always considerate and understanding (though oftentimes it's hard for me to completely understand)

Onto the sex... Now I've had sex with a whole host of different girls and thought I'd experienced it all but the sex with this girl far surpasses any of that, it's absolutely mind-blowing and she'll let me do absolutely to her. We both have a really amazing time. 

Onto the problem... To her, sex is like a weekly/fortnightly activity though i desirer it much more frequently than that. And(not to sound like a pussy) but it really upsets me when she's pushing me away and turning me down while we fool around witch then in turn really upsets her. 

I've tried talking about it with her but she's always gets really upset and shuts off, and really upsetting her is the last thing i want...

So anybody have any advise for me on this? Am i being a jerk for wanting more sex? Be under no illusions, even if this girl never had sex with me again I'd still be with her and would never consider cheating. It's just this seems to be the only problem in an otherwise perfect relationship 

Thank you for reading.
