1) we don't have sex lives, we live in constant frustration, we grow up linking sex with punishment fear and guilt, it's taboo, just like any other expression of love.

2)i could write an essay on this one but i'd say , from my personnal experience, no matter how hard i try, i always feel like a man would only be in a relationship with me to take advantage of me before marriage, because it's a cheaper and easier option, so i'm very paranoid

3) usually young adults start dating in secret, eventually if both are very serious about it they can try to officialize the situation but this is the perfect scenario and it happens in 1% of cases.
