Father got an erection dancing with adult daughter

Ah man, is this normal?

My partner and her father have a strained relationship. Over the past few years he has become very negative and unsupportive of anything she does. Three years ago he was upset that we chose to have a baby and has been overbearing about sharing his opinions on how we raise our kids.

There has been a strain on the relationship ever since, but he has been good to our two older kids so we like them to spend time with him. I found it strange that he sleeps in the same bed with both kids (a boy 10 and a girl 7) but my partner says its not a big deal. At our house they are not allowed to sleep in the same bed, why he doesn't sleep with his wife is beyond me.

WELL... recently we were at a wedding and my wife looked beautiful and dressed very sexy, which she rarely does. Her father was very rude to me, which I shrugged off... but during a father daughter dance he got an erection while dancing with my wife (his adult daughter). She was really disturbed (but made sure not to make a scene or act weird) but she said it brushed up against her and she felt sick.

Is that normal? Does this mean he has some weird sexual hang ups going on in his mind?

Most importantly, now should I worry about my kids spending the night with this man?

It is a bit odd, especially the fact he is married and doesn't sleep with his wife when the kids are there. Also for an older man to me sleeping with a 10 and 7 year old is a bit creepy to me. I unfortunately grew up around sexual abuse, to my knowledge I wasn't abused, but my siblings, cousins, aunts etc..were either by my grand father or my uncle.
I am sorry your wife had to feel that repulsion because of having that happen to her. My only thought, was he at all drunk, because that would be the only way I would excuse the behavior. Because when you are drunk things do happen but if not. I would want to press the issue a bit, especially the issue with the children.
I hope that you all can resolve this without hurt feelings. As a man I feel uncomfortable giving my 4 year old a bath or helping her get dressed. I don't even usually have her sleep with me unless we are at a hotel and there isn't an option. Hope I helped a little.

This is certainly not normal for me! I strongly advise that you do not let him sleep with your children- better safe than sorry. Also, do not allow him to meddle in your family's affairs unless his advice is required. All the best!

Yeah, he wasn't drunk, he doesn't drink. A friend of mine told me its normal... that men sometimes get erections without being aroused. I don't know - weird to me but I also do not want to judge an innocent action.
