Theyre bringing sexy back to a toddler level.

Jessica Biel revealed on Tuesday night that she and husband Justin Timberlake have been teaching their 2-year-old son Silas about sex education.

Were using technical terms we shower together, and (we say), This is what Ive got. This is what youve got. We just talk about it. I know its really young, but I really believe that if you start this early, theres no shame, Biel, 35, told the crowd at the MAKERS conference in Los Angeles, according to People.

I dont want to tell him, Keep your private parts, and this and that, she explained.

Its a beautiful thing. You have it and mine is different and its cool, man. We have to respect ourselves and respect each other. So I believe it starts really young.

Biel started the discussion after she was featured in a NSFW PSA video about sexual-education along with Chelsea Handler.

Oh my god, yes, this is liberating, Biel says in the video.

In the video, the two are encouraging women to familiarize themselves with their body parts.
