<human>: We've been dating for almost 2 months and last week she asked me how far I've gone with a girl before. I am her first boyfriend, i was her first kiss and hopefully eventuality i will pop her cherry. I didn't want to make her uneasy so i said nothing except a bj. 

I actually lost my virginity when i was 15 and had sex again 3 years ago. I was and still am ashamed of them because the only reason it happened in the first place was to seem cool. 

I just didn't want her to think less of me and I'm regretting lying because i really care about her. I'm scared if i tell her i lied she might not trust be anymore. I hope she wouldn't dump me because of it but you never know. 

Is there a best way to tell her?

Summarize the given text in a few sentences.
