Well, the message sounds innocent enough so you should be fine there. It wont be "too up in his face" really and on the part about his friend well.... not too sure. I'd say his friend may like you and may be jealous or it may have been the whole part of licking the slide. Since it was a truth or dare you may want to reflect on your own "truth or dare"'s because he may not have liked them. All in all i would send it but I wouldn't text him too much. Start off slow and don't get too personal (people often dislike this if they dont' know you too well, got to earn trust) slow and steady builds friendships.
