i notice that in general, i like prude, but outgoing girls.

usually with girls, i have no problem with initial attraction, but it eventually dies away and our relationship becomes platonic

how should i treat these "prude" females? if i treat them like i do with other women, it is possible that i come off as an asshole

i know that i should be weeding these girls out, but the problem is they are the type that i like. any ideas as to what works with prude girls?
