In most places and provided you are of a suitable age, it is perfectly acceptable. Just make sure that if you do anything more (i.e. intercourse) that you understand what you are doing and have prepared accordingly (protection, pills).
If you had intercourse with someone else and it hurt the other girl's feelings, it is not likely that you will win her back. Let her heal up and if she's interested she'll come to you.
She's just not that into you
Like in any other country, there is no reason some people won't do it.
It means that you and him will be going together and both of you will not be seeing other people.
Paolo Nutini had girlfriend Teri but then they were breaked . Now they are back together. They know each other from their childhood.

MOVE
Why were you naked with other people? If you did it with the intention of following it up with something 'more', I would consider it cheating. If (somehow) you accidentally ended up naked (together), then it is not cheating. You just have yourself a very strange story.
Get married, have intercourse once, have a baby, die together.
Then go for it! If you both like each other, just get together, and good for you.
