Ok, I know it is always a shock when a parent realizes their child may or have had sex.
This is what you do.
Do not assume anything. Condoms are handed out at different type of events. Could be it was a joke. Could be she was hiding it for someone else.. and yes, maybe she purchased it.
IF she is going to have sex, good thing she has a condom.
You tell her you are aware that some people her age are having sex. You realize it is tempting and their are safe ways to physically have sex, but what people forget to talk about is how emotional it is, and when the people break up, that the sex history can be hard to get past.
Then tell her your feelings about how if she is having sex, she would be honest with you, because you would prefer she wait, but if it is going to happen or this is going on, she needs birth control and she needs condoms. You also want to make sure the emotional part of her is also protected.
Many women feel like with sex they are giving a special part of themselves physically, but also emotionally, way deeper than MOST men.
So when this relationship ends, women internalize this. This is the heavy burden.
Did he drop me and move on because - "because I am not a good person?"
"Was I a challenge for him? So he wanted to win me as a prize? "
" Should I have waited?"
"If he respected me (or if I was a respectable person should I have refused)
This is a lot for a young person who has not found who they really are and what they totally want in life.
I would rather young people who are thinking about or are already sexually active have protection, than to just have unprotected sex.
You are too young to be a grandmother. Remind her of this. Talk with her
so she will feel like she can be honest and safe speaking about this.
