To be creeped out???

[Orangewater33]

Long story short - met a guy at the park a few weeks ago with his son 4(same age as mine) and his daughter(22) he is 56 I am 34.
He asked us to go for a playdate with him and another mom, I agreed but she didn't turn up and we spent the day at his alone with the kids playing.
Had a second visit where we went to the library and then I called to his house last night(we live close) and he asked us to stay for dinner.
Things were fine and the boys were playing when he came out of the kitchen and I was holding his electric wine bottle opener.
He walked in and said 'it looks like a big dld'..
I was like - 'does it?' already feeling uncomfortable..
He kind of scoffed as though I was being prudish and then proceeded to start talking about orgasms, sex and how he respects women who enjoy sex even though most guys think they're w**res'..
I don't know why, maybe just a culmination of multiple things but I just feel really disappointed..
Why do men seem incapable of behaving in a respectful manner? Am I just being prudish? I hate that feeling when guys do this and they think it's totally fine but we're sitting there alone with them starting to panic a bit and wondering what to say to get out of the situation..
If we go along with the convo we're up for it...if we don't we're prudish and frigid..
Hope it's ok to post this because I could really do with some thoughts on it :/

I think it's unwise to go to anyone's house alone after just a couple of meetings if you don't know much about the person (e.g., they can't be easily traced such as have a child at the same school as you).

Surely by definition if you're going to someone's house then they can be easily traced. You may not know much else about them, but that's true of many people you meet at the school gate too. In theory any normal social encounter can go wrong behind closed doors.

I'm going to take a wild guess that many of the people on this thread who are judging the OP for going to a "stranger's" house have let their children do sleepovers in households they hadn't met and vetted every member of.
