Sex with a friend

well i was 14 and i was at a party i was slightly tipsy and a girl who i knew for years who was 16 at the time and she was tipsy too. She was rubbing my trousers around my penis area and grabbed my hand and led me into a bedroom. we had foreplay then we pulled each others clothes off and had sex. It was amazing as she already had a few sex with about three other people and i still keep in contact with her and she didnt mind it at all as she was tipsy and it was the best time to lose my virginity to a beautiful person like her. Does anyone think this is wrong as i knew her for about 12 years of my life
