If number two dont do it for you then he dont do it for you very simple really, so I would let him down gently but leave well alone.

As for the other two and being candy good luck to you I dont see age as an issue and they certainly dont so whats the problem ?

I would go light with both untill you or they choose then stick with one of them as runing two boyfriends with limited time is confusing like my post lol.
