They'd make a good present for daughters who are at that age too, on two fronts. One, it would allow your daughter to comfortably expand her hymen at a slow pace so her first sexual experience isn't painful...or messy. Two, it would probably reduce teen pregnancy because girls could deal with those hormonal urges without shame, guilt, or putting themselves at risk while learning about their own bodies.
That second one applies to boys too. A fleshlite would .make an excellent gift for a teenage boy.
