I think that there is a male analogue - many adolescent boys would have had posters of particular female stars on their bedroom walls (or, if they were somewhat shyer *cough* just have carried a torch for one). I think there is a difference: it seems that we might well have quite deliberately chosen targets for our youthful obsessions that were even more unattainable than rock stars! I think that's probably true for most girls, too - I don't imagine that a very large proportion of girls with David Cassidy (or Justin Bieber
) posters on their walls would actually wish to end up having sex with them.
And, by the time boys have reached the same level of emotional maturity as girls (I've seen it suggested that boys might attain the level of emotional maturity girls exhibit at 14-15 by their very late teens or early 20s), they're significantly older, and less prone to having their naivete taken advantage of.
I can remember, as a fairly young person, seeing footage of girls at Beatles concerts - that classic shot of young teenage girls in Edna Everage glasses tearing at their hair, sobbing, and being carried, limp, from the auditorium - and being quite shocked and utterly perplexed by what was going on. Even as an adult, I find it difficult to relate to the kind of emotional state that was being demonstrated in that footage, but it's undeniable it went on, and still, perhaps to a slightly less intense level, does.
