<human>: So I have been dating this girl I met last December for 5 months and things couldn't have been going better. But tonight I decided to go and tell her that when I was 6 me and my then best friend (a guy) kissed and gave each other blowjobs. We were really horny kids. She acted fine about it for a while, but then started saying things like I should always tell this to girls before I kiss them and that I should lure them into a relationship and have them fall in love with me before I tell them this so that the girl cant run away. (she was talking about us and being sarcastic) We just told each other we loved each other on Wednesday. So she just now said she was going to bed and I said night and she said bye. What should I do? I know this is a secret I should have kept for life but I didn't, and I cant take it back now. I really love this girl and I don't want her to leave.

Summarize the given text in a few sentences.
<bot>: I kissed and gave my then best friend a blowjob when I was 6 and just told my girlfriend, and she got mad at me for telling her and for not telling her sooner
