If any of us offered sex to a 13-16 year old boy, they would be happy to oblige.
Women don't tend to do this, even though we have as high a sex drive as men, why don't we?, because it isn't right to take advantage of anyone vulnerable/immature, in any way.
This should be written into law (as it is) in a civalised society.
If you cannot control who you have sex with, go and get help.
All the excuses made for men, makes me wonder if we should be keeping them in institutions and not be allowing them to roam freely, if making the right choices is beyond their control (DV, Rape, grooming etc).
" I look back now at how I behaved as rather cringeworthy and immature, but fairly normal."
Yes it is normal to go through that stage, what isn't right is that any adult around you would abuse their power (that they have as an adult, let alone a teacher/doctor etc).
You cannot describe any girl under 16, as predatory, teens that target younger children are damaged. You have a range of normal sexual flirting, that teens go through and then you get, damaged teens, who become promiscious, that need protection.
