Should I be trying to have more often?

Well is different for everyone, frequency and style different in every relationship. There are really no wrong or right amounts to draw lines around. I mean I have been in functioning casual relationships before, but it's just not really my thing either. Call me crazy, but is just more enjoyable when you truly care for the other person. When I'm not in a relationship, I'll go for extended periods of time without, but within a relationship, it's always unique, different frequencies and styles.
