I'm attracted to children. Is this going to put a strain on our relationship?
Really, you have to ask? Since when have you had these sorts of feelings for children?
I have been attracted to children from a young age.
It's unacceptable to be attracted to children. You should find someone closer to your own age to be attracted to. There are plenty of beautiful people out there to fall in love with.
I can't help it.
You should take yourself to the nearest therapist and talk to a professional to try to understand your attractions. It is unhealthy to be infatuated with minors, but if you talk it through, you might be able to resolve and fix your unique tendencies.
