I don't know how we got onto this last night, but 18 year old daughter and I were having a chat, and she opened up about it.
When she was in first year of secondary school, she was at the swimming pool with two of her friends (I wasn't there). A man was in the swimming pool with his little daughter. My daughter estimated her to be 2 years old.
The wee girl was captivated by my daughter and her friends, and they were being nice with her, chatting and playing. My daughter said that the dad was acting a bit creepy towards them, so they moved away. Shortly after, he got out of the pool with his daughter, and was clearly erect.
I don't know what I expect any of you to say. I don't even know why I'm posting. I just feel disappointed and angry that this happened to my daughter - and her friends - and that this happening to a grown man was her first experience of what it means to be sexually aroused.
I also wonder about his daughter and hope that she is ok 
No man in his right mind would think that it was acceptable to leave the pool like this.
