You're misappropriating your terms: You are saying "afraid of adult sexual relationships" means "sexually immature." Thus, if they are sexually mature, that would mean "not afraid of adult sexual relationships." And then conclude, if they are not afraid of adult sexual relationships, then men/priests "not afraid of adult sexual relationships (i.e. sexually immature) ought to engage in the above mentioned sex acts. Because you start with "immature" they (men/priests) should not. Your qualifier is that because they are immature they shouldn't, so then if they are "mature", they should. Your qualifying the behavior by the underlying qualifier: Only sexually immature men/priests, and which leaves out those not afraid of adult relationships out of the question if they shouldn't as well. Again, the statement should say: "Men_priests_and_not_engage_in_sex_acts_with_children_and_teens." I'm trying to help give you a better premise for your argument.
