My Mother

Hi
So,in the last few years I've been noticing that my mother,in a friendly and not threatening way,that she have two sons,that are men and are going to date woman.
She says that in a friendly way and sometimes in random occasions(at least she doesn't say that too much,very few times).For me it looks like she really want a good future to me,but unfortunately,is not the future I want to myself.
Yesterday I said that it annoys me when she says that,and she didn't understood why(I didn't said why).
Should I wait till she says that again and talk to her(and then come out)?
Yesterday she also said that she wish to be born a man in her next live(of course,a joke because of period and stuff),and I almost said that if she wanted we could trade our "parts" XD
I should have said something....
Bye^^
