You're just scared, and that's ok.

I don't think there is any need to write anything about specifying your intentions on a profile. Just put yourself out there, start dating, and see what happens. Sometimes you won't click at all, sometimes you'll get laid on the first date and won't ever call her again, and you just might meet the love of your life.

You don't really even know what you want. You just need to have experiences. Have fun. Be nice.
