I'm 16 years old and my 15 year old boyfriend and I were fooling around a bit. He rubbed the tip of his penis on my vagina, then barley inserted the tip of it into me ( I would say at least half an inch or so). Nothing was broken, no blood, what scares me is that I'm not sure if there was any pre-*** on it or not at the time he put it in. If he did have some, there wasn't enough to drip inside me (like it was just on the opening of his penis and not seeping out) thing is it all happened so fast so I'm not fully sure. Because I do remember there being some on it, though if it was still there by the time the tip went in, I have no memory. This all happened yesterday-I've read many places saying I have a VERY slim chance of being pregnant, but should I take a pregnancy test anyway just to be safe?

Its FAR too early to take a pregnancy test. Wait until you skip your period. And, yes, there is a possibility you could be pregnant.

You are aware he is underage, right? I doubt they will/would but his parents could attempt to press charges against you. Every now and then it happens.

But back to the pregnancy scare - the only way to know is to give it some time. The lecture is that it's not a good idea to "fool around" (and I see little difference between what you consider to be "fooling around" and the rest of the world considers penetration) unless you are protected AND are prepared to handle a pregnancy if the protection fails.

NOTHING is 100% effective.

Chance are slim - but it is possible.

Yes depending on where you live, 16 is often the age of consent ( but not all places) and if he is 15, charges can be pressed against you for having sex with him.

** and yes that was sex, since he did go in.

And often there is no blood since the hymen is often broken long ago with tampons, exercise or other activities.

But yes that is all it takes, but you will have to wait as noted in the prevous answer

To clarify anything, he's turning 16 in about 2 weeks. And it wasn't full on penetration, he didn't go in and out furiously, he stuck the head in not even an inch and kept it there for a few seconds without even ejaculating. But as I said, there may have been some pre-ejaculation on the opening of his penis, but I just wasn't sure if it was enough to get me pregnant if any of it somehow did get in me with such a little amount and since it wasn't completely in me.

ONE sperm is all it takes to be pregnant.

There are MILLIONS of sperm in ONE DROP of semen. And yes, pre-ejaculate is semen.

Welcome to the world of being terrified until you get your period.

PS--1/2 inch or 6 inches in, it's sex. NEITHER of you is still a virgin anymore, if you thought you were.
