Is this considered kinky?

Nooo way are you kinky! Those are the kind of things that are really great.

NOTHING is kinky if the both of you like it.
There are NO stupid questions. A lot of us wonder what the other people are doing and like.

NO it's not a bad thing. HAVE FUN but be careful.

No, just don't expect every guy to know these things don't be afraid to voice what you like. Don't be afraid to show him what you like. Since some girls don't dig these things and some do it can be upsetting playing a guessing game with what a girl does, and doesn't like. Only about 10% of the girls I've been with where deep into the bitting and being rough thing like that. So, yes some are, some aren't. Once again like I said, so because of that, letting your partner know you are into that can't hurt. Although make sure you set pain limits through showing him how much is too much, or if possible by telling him how much is too much.

Hun I don't know a women who doesn't love being bitten every once an awhile and as for getting your nipples sucked/bitten. Most women LOVE it and crave it!

It's not a bad thing at all . if it makes you feel good then continue doing it! Cause in the end that's all that matters.

nah it `s normal! kinky is like biting and slapping and handcuffs and other S and M things but your 18 so I don`t want to express tooo much just be safe and have fun with you and your S/O :)
