Sex and a Great Relationship

One thing I've been wondering lately is probably not something people wonder about on a regular basis.   I mean, people in a healthy relationship that aren't teenagers or emotionally stunted humans without real intelligence. 

My relationship with THE BOYFRIEND is going so well.  We spend time together when we can, we both show each other how much we care for each other and we just don't want to fuck it up somehow.  So, why am I wondering if the way things are with us ... is normal.  Is this how healthy relationships progress?  What I mean by that is that to me it feels like we are slowing down.  The excitement just isn't there anymore.  No, that's not what I mean.  It's not boring.  I still laugh with him.  He still challenges me intellectually.  Sex with him is still great, when we have it.  And maybe that is the question that is lingering in my mind. 

Men are supposed to think about sex all the fucking time, right?  So, why don't we have sex more?  I am a very sexual woman.  Not going to deny it.  I know how to use all the I have, how to flirt and tease, I love having sex a lot.  It is one of the ways that I bond with someone; probably the most significant way.  With THE BOYFRIEND, I want more.  I'm tired of the not exciting way that we start having sex.  Laying down in bed, cuddling naked.  It's always the same progression, too.  Go down on him, move up to straddle him, I orgasm, put a condom on, he finishes. 

That's the reason why I couldn't finish at all today.  It's always the same.  I need change in my sexual routine.  I need passion.  It seems to be lacking from our relationship.  I don't like predictability in my sexual routine. 

Is it because of our different schedules?  His overnight shift?  Or maybe that is just the way that he likes it?  Or is he just not stimulated by me the way that he used to be?  The latter is what I am most afraid of, and the thing that I also don't think to be true either. 

Am I just too used to a fucked up relationship to know what to do in a healthy one?  I honestly don't think so.  I think we have just gotten into a sexual rut and don't know how to get out of it.  I'm not going to confront him about it and be all broody and moody.  Just slide it into conversation somehow. 

Yeah, that'll end up really well...
