Hmmm I can definetly understand how that'd be frusterating! But if every other part of your relationship is great, and he tells you you're beautiful.. I wouldn't worry too much about it. Some people are "take charge" types. He just dosen't seem like a take charge kinda guy. I bet he probably dosen't take the lead in making plans either. I can see how it'd make you feel unwanted.. but really.. if he didn't want you, he wouldn't be with you! Noone is forcing him to be with you!

If i were in your position I would maybe just not initiate at all for a while.. That way if he wants it (and he will) he'll need to do some work too!
