Confused... does this mean I'm turning into a slut?!?!

Well slut is obviously a subjective term. Like you said, to some of your friends, you're innocent, but to your other friends, you're turning into a slut. But sounds like you are the one that has a problem with it. If you don't like what you're doing, then don't do it.

Ummm. Slut is generally a sex negative term. It doesn't matter what you do, it is more a matter of if they approve. Other people's approval should not be part of your sex life. Find more mature friends who understand that sexuality is a part of being a healthy human being and not a ongoing battle with shameful urges and feelings.

Your still young. But let these words stick with you for the rest of your life.

Your life, is what you make it, whatever it is that you decide to do, day to day, year to year, you have to live with it. So do things that you are proud of, or remind you of love.

Good friends will defend your reputation, bad ones will start rumors.
Good friends will try and tell you the truth, bad ones will encourage malice.

I will just give you the attributes of a slut:
-Think they are the middle point of the world
-Think they are better then everyone
-Loves to make out with everyone handsome and/or rich no matter the personality

Losing your virginity with 1 guy you have been with for a long time and you truly love does NOT make you a slut.

Losing your virginity with 1 guy you don't even love and 1 week after making love, you break up with the guy and start making out with another guys. That does make you a slut.

I can't help but assume that you're pretty young, for various reasons. regardless of age, why does it matter what your friends are doing? NEVER think that what they're doing (or not doing) is what you're supposed to be doing.

A slut to me is someone who doesn't respect themselves at the end of the night. they f*** around with guys just to impress them or as an attempt to build higher self-esteem by being praised by guys. (doesn't work). but if you're doing things with guys you have to think of a few things first, how well do you know this guy? Guys won't see you as dating material if you're ready to spread 'em at the blink of an eye. Are you being safe if you do choose to go further? You have to, have to, HAVE TO, be safe. use condoms. And ultimately, who are you doing this for? Don't ever do something sexually to impress someone, if you're getting physical with someone, you need to be doing it for the sole reason that it makes YOU happy, this what you're ready for, etc.

You are not a borderline-slut, your friend seems more interested in condemning you for getting further then she has. Either she has really strong morals, or she's feeling a little bit of jealousy. Either way, it's not really her place to tell you what you're ''becoming''. Regardless of what anyone's saying, as long as you're being safe and know the guy well, and you're happy with yourself at the end of the night, it doesn't matter what they say.
