opposite gender twins.

[birdbrain01]

do you have a twin of the opposite sex?
what's the gender of your twin?
who started puberty first?
how long after did the other twin start?
how old are you both?

I do not have a twin.

[Vermilion]

I have a twin but we're both males, 17 years old
I think we started the same time.

^^ thanks I'm just curious about this.
I'm also interested in girls responses to this.
