I would say it's not so much that Satan is enticing you when you're alone. Rather, the opposite: the holy spirit is holding your hand and guiding you when you are with the real-life boys, so you are not experiencing temptations to impose your adult sexuality on them.

As Eldad says, if you really single out one boy and focus on him, you could end up finding out that you have to do some real work controlling unwanted urges about him. I think younger adults may really risk being overwhelmed in this situation.

As for me, being decades on not just in life but in monogamy, I am sure the holy spirit will always guide me to put the boy's interests first. But you have to be very honest with yourself about your own situation.

Also, keep in mind that drinking or smoking pot may really change your ability to evaluate situations and stay on track.
