I have mentioned in the past that talking with your children about your own sexuality is generally a bad idea. However, there may be times when it is warranted.
The blog Sexuality In Art recently reviewed a graphic memoir called Fun Home: A Family Tragicomic by Alison Bechdel. The story is centered on Alison as a young girl, coming to grips with her own sexuality and budding homosexuality and her father's closeted homosexuality. It sounds like an astute and honest look at emerging sexuality and sexual awareness.
Alison portrays a time and a place where it may be appropriate for a parent to open up and talk in some very general terms about their sexuality. Alison appears to be grasping for that very conversation, trying to lead her father into it, however clumsily.
Looks like it might be a great read, well worth the time of anyone trying to understand a young girl, particularly one grappling with homosexuality, either personally or in her family.
