Questions: Family & Friends

I just got a new house that has a pool. There is an 8 foot privacy fence.

I pi have started to prefer to swim naked. This afternoon a couple female friends are coming over to hang at the pool. I am thinking of swimming naked but don't know if it would bother them. I am trying to get a gauge of what girls in general would think. I have a good body if that makes any difference?

OK, I know that it sounds weird but I said SLEEP, not HAVE SEX. Me and my sister live togather (she's 22) and she has generalized anxiety disorder (probbably coming from a dysfuntional family) and has trouble falling asleep alone and even if she does, she usually has nightmares. So I let her sleep in my bed with me and we cuddle. She likes to tuck her head between my chest, chin and left shoulder and hold her teddy on the other side of my chest. I wrap my arms around her and will run my finger through her hair and reach under her shirt and rub her back to help her fall asleep. a lot of people think that it's wrong but I don't feel any sexual feelings when we're cuddling, but feeling her soft hair and skin is very relaxing for me and holding a warm person just makes me feel better. For the lack of a better analogy, it's kind of like cuddling with a pet in that you feel relaxed but not aroused. What do you think, is it wrong that me and my sister do this?
