<human>: Can you condense the text into three sentences or less?

So I find this is a pattern that I encounter in all of my relationships I've had. We go from having fiery passionate sex to well... now instead of both of us commenting on how we want to fuck each other it has turned more into a "aw you're so cute" type of phase.  
  
At first I was fine with it, but it's starting to feel that doing this has definitely turned down the passion. This happens in every relationship I'm in and we go from having sex everyday (which I know isn't always sustainable) to like... once.. maybe twice a week. Is this my fault in that I'm not doing anything to make my SO "yearn" for me or is this just the natural course that relationships take?  
  
I ask this because it leaves me feeling a little less like a man since my woman isn't constantly after me like she once was. I know that's maybe not the best way to look at things but honestly I can't help it. This has happened in my last 3 relationships and I'm starting to wonder if it's me who is doing something wrong. This has led to several mismatched libido conversations and it's sort of killing me. I don't want this relationship to end because of it.
<bot>: I'm finding that I'm too cuddly with my girlfriend and it seems to be leading to less sex. This is a pattern I've just noticed over time. Am I doing something wrong here?
