I lost my virginity at 19 and dad finds out when im 20. tryna make me feel guilty that i lost it. WTF is up?!?

i lost my virginity (V) at 19 and my dad found out when im 20. i made sure i had correctly with a good girl and it was a success! but word of mouf got to my dad and he was disappointed that his son isnt a V anymore. it seems as if hes tryna force me feel guilty that "i lost my V to sum 'stupid tramp' " by his word, but the girl ONLY slept with 3 V's (her way of being safe and he doesnt kno her stats) before me. hes doing this by constantly bringin it up as if it was the worst thing ive done since i stole sugar outta my grammas cupboard when i was a baby. any help??
