It can be. Don't rush into romanic relationships. Get to know the persons tendencies and personality BEFORE letting your guard down. You will save yourself a lot of heartache. Take it slow...let relationships flow organically. It no fun if you are worrying and trying to control everything!
Sometimes. Sometimes no. I've had it turn out good and bad. Thinking back, if they're good and respectful guy, would you really want to complicate it with physical things so quick? If they're not a good guy underneath it all, do you want to them to get what they "want" from you? Going quick emotionally is usually alright as long as they're on board with you.
