So I'm 16 and about to start college, and I'm dating this girl who's only 13, and I love and care for her so much, she has issues such as depression etc.. But I'm not in it for the sexual interactions, me still being a virgin anyway, and she is so mature for her age it's unreal, she's not even a virgin, her mum knows about me and is okay with it, but I'm afraid of telling mine because mine are very old fashioned and not easy to talk to... I love her to pieces, I just wanted to know if it's actually 'okay'
