Same thing with me! I began telling people starting at school, my lesbian friend was showing how she hides her chest while doing drag etc, and seeing how interested instead of repulsed the group was i gained enough of a confidence boost to flat out say everything about myself and have been greatly supported since, even light banter with the group, such as being a member of the gamer club friends pipe off saying "you got owned by a girl!" and being claimed as Misty's little sister now, etc, everyone is so helpful, i was shocked at the reaction! but so glad ever since!
Glad to hear it worked so well for you!
