Oh you are wise xyz123! I like you!
It sounds like you are on the right track. They do indeed seem to wrapped up in the "new toy" mentality right now. Not much to do around that except sticking by the female and reminding her she has control over the situation not him (control should always be dictated by the one is unsure or who has issues coming up or who is just plain scared, as far as I'm concerned. Not the one who is rearing to go. Very dangerous that way!).
I guess really there is nothing more to do except reiterating the fact that you are not interested and keep trying to educate them so they can reduce the chance of getting hurt. Beyond that they are on their own path.
