Was There Ever Any Brother/Sister Action on "The Brady Bunch"?

Didn't the Brady's sleep in separate beds? Back then they all did. I don't think having a crush on your half-brother or sister would have been appropriate. I do remember watching the Brady Bunch and I liked Marsha you know the one Jan felt everyone liked (well they did) no offense Jan. Greg was fun but I thought couldn't act very well. The dad was gay and I'm sure everyone in Hollywood knew it. I loved Alice the housekeeper now she made the show.

I always kind of wondered why there wasn't ever some Greg and Marsha crushing... it would have had to happen in the very beginning when they were first getting to know each other but they were teenagers. Or maybe Jan developing a crush on the older, handsome Greg... I don't think it would have been unbelievable but like I said, it would have had to come earlier in the show.

I read Maureen McCormick's (Marsha)book "Here's the Story" where she reveals her and Barry Williams (Greg) had dated during the show for a short period of time. I remember the chemistry that was happening while watching the show between the two of them. Even though they were playing brother and sister I could see it and feel it.

I don't even think there was any action between the Brady parents!
