mother and daughter sex talk

My mom told me that I can have sex at 17 because she thinks it's more of a appropriate age and she also lost her virginity at 17. But.... I lost it at 16 with my boyfriend. I had to tell her due to stress and worrying because I was worried about something with my body (like pain and itching with my pussy. I thought I had an STD or something) so I felt the need to tell her. She wasn't happy of course even though I was being responsible, that didn't make her feel better but she told me not to have sex anymore and wait longer until I turn 17.  Well... I'm 17 now. She told me that I can talk to her about letting her know that I'm ready for it and I want to have sex... how the FUCK do I approach her about this?? LMAO I feel it would be weird to jump out and say "OKAY MOM IM 17 CAN I HAVE SEX NOW?!?!!" No way hahaha. So... someone gimme advice? As a teen, how did you tell to your mom that you want to have sex or that you're ready to have intercourse with your partner?
