When I think of types I think of people I tend to fall for the most or easiest.
Usually guarded, shy-awkward dudes pique my interest most. I always want to figure out what's behind all of this and explore a bit. I guess the type that you have to help give a push outside of their shell. Especially if someone is interested in "different" things. I really like humorous, silly, or witty people who are still reserved.
Physically I usually go up for slim to slim cut dudes. I don't really care for lighter skin men.
