I want to have sex with him now, but i'm not sure if i should.

Me my boyfriend were laying on my bed naked together
He was lying ontop of me we were just dry humping kinda thing,
Cause he knows I don't want to have sex yet.
the tip of his penis went in my vagina as soon as it happened I put my hand on his...

back he pooled straight out was like oopies
I've never had sex before, but he has, many times.
We;ve been going out for about 7months.
It actually felt really good when he went that little bit inside me, even though it was only for less than a second.
I want to have sex with him now, but I'm not sure if I should.
I love him he means everything to me, I'd do anything for him
The only thing is.. I'm only 13. he's 14.
Should I do it? Should I have sex with him?
I want to, but I don't want to get called a slut shit if people find out I had sex with him because he's most probs going to tell his friends.

You're questioning yourself...that right there should give you your answer. No you shouldn't have sex. You should only have it when you're100% sure that it's what you really what, when your 100% sure that you can deal with and live with the consequences of having sex...including pregnancy and STD/STI's.

if you are not sure, don't do it! wait til you are emotionally ready

your clearly not ready and you said that he meant everything to you, but you also said that he will tell his friends and if thats the kind of thing he does I dont think you should even be with him, he clearly doesnt care very much about you!! sorry its just how it appears...
find someone who wants you for you and enjoys being with you not this guy who just seems to want a fuck!!!
