Is it normal that me and my bf are normal seeing each other naked?

Ok so just to make it clear im a guy and my best friend is a girl.

So one day we were walking home from school and she told me "hey lets go to my house cause my parents aint coming till tomorrow." I agreed so we went walking. We got there and we went to her room and she took her jacket off and i took mine off too and i had shorts under my joggers so i took my joggers off and she said "hey lets play jenga, every time the tower falls the person that made it fall has to take a peice of clothing off." i agreed and we played until i was only wearing shorts and boxers and she was only wearing underwear and a bra. We played and she knocked the tower down and took off her bra but she said "Your gonna see my boobs" i said "just take it off ill be naked at some point" so she takes it off and we countinue and i knock it down and i take my shorts off and then we play one last round and she ends up knocking down the tower and she takes it off and i say "i win" and she says "just take off your boxers" so i do it and she sees me naked and we just look at each other and she just randomly says "can i touch it?" and i answer saying "unless i can touch your boobs and your.... You know." and we both touch each other and we get bored and just start teasing each other to the point where we were gonna have sex and i start rubing my dick on her vagina and i stop and i say "this is to far" and we put our clothes back and and i tell her that i have to go and she says "ok, but someday stick it in me"
