You embody the German principle of Konstantzusammenschaft, which is best described in English (without using the obscure English word "sammenschaft") as "eternal togethermanship".
The Loverboy Random Gentle Love Master (RGLMm)
Well-liked. Well-established. You are The Loverboy. Loverboys thrive in committed, steady relationships--as opposed to, say, Playboys, who want sex without too much attachment.
You've had many relationships and nearly all of them have been successful. You're a nice guy, you know the ropes, and even if you can be a little hasty with decisions, most girls think of you as a total catch. Your hastiness comes off as spontaneity most of the time anyhow, making you especially popular in your circle of friends, too.
Your exact opposite: The Billy Goat
Deliberate Brutal Sex Dreamer
You know not to make the typical Loverboy mistake of choosing someone who appreciates your good humor and popularity, but who offers nothing in return. You belong with someone outgoing, independent, and creative. Otherwise, you'll get bored. And then instead of surprising her with flowers or a practical joke, you'll surprise her by leaving.
