It varies from guy to guy, no universal answer is out there for how to approach a budding relationship. Personally I'm an absolute romantic and tend to be very philosophical in my interactions with a woman that I like. I'm in no rush to jump in I want to get a feel for her, her mentality, her likes and dislikes, her interests, aspirations, attitude, reciprocation of emotions, etc. As best as possible I want to know that we stand a good chance of getting along should we take the next step. I'm not one for casual flings and lusting after every sweet scent and swaying hips, that creates too many problems in the long run, plus it feels pretty empty when you go down that route. So in summary, yes, I take things slow and want to get to know her on a deeper level if I'm feeling her romantically. I never let the looks get the best of me, there is more to the relationship being successful in the long term if you know more about her before pairing up. Hope I helped you to garner some insight into at least one guy's perspective on romance.
