I’d not call him sperm donor as actual sperm donors have legal rights protecting them. Having unprotected sex and thus running a risk of conceiving a child isn’t being a sperm donor.

I can’t imagine a young girl asking to get into shower with her undressed father. Are you sure it wasn’t him asking her to climb in?

We have a 8 year granddaughter I cannot imagine she’d say grandpa I am going in there with you. Why?

I don’t think one needs to have experience with children to know that a guy being fully naked in front of 5-6 or 7 year old young lady is weird to say the least. Why would he even think it was a good idea. Is he a nudist or something?

Also i find it curious that it all happened because “she wanted it.” What else he’s going to say happened because she wanted it

I don’t know if he did anything or not. And it really is hard to prove such things if there’s no physical harm. I trust my husband with my life but I’d be grossed out forever if I found him naked in a shower with our granddaughter.

No I’d not keep my findings to myself. If you plan to raise children with this man you owe it to them at the very least to know more details and hear it from him. Sometimes truth reveals itself.

And I would not count on you being there and keeping future kids safe. You won’t be able to be there 24/7.
