I'm a guy and if he truly wants to invest himself and has good intentions with you he will wait as long as you need. For me, personally, when I'm really into someone it's usually the furthest thing from my mind. Not that I never think about it, but would I push it on someone I'm really interested in just to run the risk of making her think that's all I care about? No. Because I want more with that person than just sex. There's nothing wrong with taking your time. If he can't respect that then I guess you can see where his intension's with you really lie.
