Can a 16-year-old date a 32-year-old?
Yes and no in Pennsylvania. The laws about this are a bit confusing. The age of consent is 16, so having sex with a 16-year-old won't get an adult charged with statutory sexual assault. What's confusing is that until the younger person turns 18, the older person could still be charged with corruption of a minor, which is a third degree felony.
So, according to Pennsylvania, a 16-year-old kid is perfectly capable of consent to sexual activity, but if they have sex with an adult, their morality will be corrupted. To me, it seems like they made a new law and forgot to take an old law off the books, so now it's just a mess.
Also, if there's a power imbalance in the relationship (for example, if one person is the other person's teacher), then that's institutional sexual assault no matter how old everyone involved is. Just thought I'd make that clear, in case any students are trying to go out with their math teacher (why anyone would want to, I have no idea).
