When am I ready for sex?

I am a virgin (and a 16 year old girl) and lately I have been feeling really horny and I fancy every good looking boy in my year. Me question is that even though I feel very mature for my age (and I am very sensible and would not do anything I am uncomfortable with/ I will always have safe sex) am I ready to have sex? I know that I would only like to have sex with a boyfriend (when I get one) but do you think that I could be ready for sex when that happens? Ps. How old were u when u lost your virginity and did you feel ready? Thank you this would really hel I just feel very new to this stuff and want to get it right (and not have any regrets)
