What should I do - I think I'm Bi?

I told my mum when I was 13 that I felt attracted to girls, (and had been for some time) didn’t surprise her at all, she smiled and said she suspected I was having those feelings, we had a good chat about it, yes she said the usual it might be a phase stuff, (which it could have been) but was also quick to stress that my feelings were normal. I’m now 16 and those feelings have never gone away. I’m completely comfortable with my sexuality, as are my family and friends.

The best thing I think you can do is try to choose a nice quiet moment when everything is relaxed to just tell your mum about your current feelings, it’s best not to do it when things are hectic and normal daily stuff is going on. Just explain to her that you’ve noticed an attraction to other girls, you could say that you know it might be a phase (which it could be) but tell her in a calm way that you are comfortable with it, that you’re not worried about the feelings you have.

As for your friends, slightly different I think, and yeah, maybe it’s best to just tell in amore casual way. I told my friends as we were walking home from school one day. They were fine with it.

You sound like you have good friends, so it should be cool. And if they do feel awkward at first, just give them time to get used to it.
