It is normal that i like to be seen nude?

Go to vegas be in peep show. They make big bank.

I think it's normal. But for me, it depends on who is going to see me nude. I wouldn't be turned on if a bunch of random people see me nude, but I would be turned on if me and a special one are in a room alone and I'm nude in front of him.

it can be quite a turn on.

i use to let strangers watch me on cam - never my full face though. sometimes let them watch me suck and lick my own nipples.

knowing how hard they were getting off on it got me even more aroused. i remember dedicating a few (ok many) licks and sucks to some of them

Try a glory hole

I'm in a kayaking club at university, in which nudity is a standard part of any drinking session...for everyone! It is undoubtedly a stark controversy to the rest of my life, but I think as a consequence, or frankly being used to being around lots of other people naked, it doesn't seem out of the ordinary to me and therefore not a turn on...

well I live in country but I have some neighbours, and often I leave windows open to allow others to see me

I suggest finding an apartment with windows to act out your exhibitionism.
It gets even better if you have neighboring apartments and I hope you're visually appealing.
