Is it normal to be weirded out by really close family members?

I've seen all that and lots more. My ex and her brother use to get it on. It was normal in their household. I know they were an Incestuous family.

Seems like it's "normal" for them.

I dated a girl from a similar family when I was in the army. I was 19 at the time and she was 17. The whole family mouth-kissed including her 16-year-old sister and mom kissing me. Their dad thought swimsuits were a waste of money so everyone swam in their clothes in the lake on their property. (That was where I learned how sexy wet blue jeans were!) He also thought sleepwear was a waste of money so everyone slept in their underwear and ran around the house like that at night and in the morning. When I first started seeing "Lisa" her mom would usually have a housecoat on if she was ready for bed, but after a while she stopped caring if I saw her in her bra and panties, (or less). Her sister and her mom both teased me sexually in front of her dad who didn't seem to care. (It never went beyond that, but her mom looked like she could be an older sister and I did have more than one dream about all three of them together with me.) I was invited to stay with them for a week in the summer when I was on leave. "Lisa" was encouraged to stay in their basement guest room with me and have as much sex as we wanted. Every morning, her mom would wake us and her sister up and we would go for a morning swim in the lake in our underwear. I eventually found out that the women of the family were just submissive and believed that if the men of the family were happy, the family was happy. I was on track to marry her, but we had a stupid falling out after she went to college. I often wonder what happened to her.

I think every think you said as an exemplar is normal! Your just not familiar with a family like this, they just have a different culture or habit as them. But they are normal

I think the behavior of the families you're talking about is normal... and the way you feel is normal especially if your family is kind of disconnected. But some families are just close. I realized the other day while I was watching youtube videos on the couch with my male cousin (and I'm a female) we were basically snuggling while looking at the little screen. I kiss my uncle and Grampa on the cheeks. I think some families are just like that. It may have to do with culture too.

This type of stuff freaks me out too.

I bet they're freaky in bed.. try giving him a bj and have them watch and maybe take care of u in the process.

Weird question is weird, but does the mom walk around the house in her underwear with other family members around? If that's the case, then that's the weirdest thing on that list (At least in my opinion).

All of those are pretty... unusual, except for "Brothers and sisters going to bars together". What is wrong with that?

Pretty gross, yeah.
