Should i have sex ?

I am with this guy at the moment , and I really like him . we have been going out for about 2 weeks now , although have been out before for about 2 months but just 'took a break'. its his birthday at the end of the month and he wants to have sex with me....

I dont know what to say because although he has cheated on me before I still realy like him and want to have sex with him, but I dont know if I am ready or not. I think I am, but I am not sure if he is using me.
I d realy like him but he is 16 at the end of the month and I am 15 in september, so I have to do it before his birthday or not at all till next year, by wich time he would have got bored and probably left me, becuase I dont think its right to have sex with someone over 16 iy you are still under 16.
I dont want it to be one of those things where he breaks up with me afterwards, because 'there is nothing left to wait for' but I dont want him to get bored with me if I dont. I do realy like him and realy realy need help. I dont know what to do. if my mum and dad found out that we had had sex when we were both underage she probably wouldn't mind, but if she found out we had and only I was underwage and he was 16, she would kill both of us and probably go to the police.
please help me
thanks

only you can decide if your ready, if your not ready, then dont have sex with this guy just to please him. if you really want to have sex with him dont be surprised if he does end up just using you. from what it seems like he just wants to have sex with you. but if he really wants to be with you, he will wait.

but always use protection! XD

obviously this guy is a realll dick. if he cheats on you, then expects you to have sex him with, hes not worth it, hun. save your sex for some other guy. who actually deserves you.

No you Shouldnt
If you do it hes going to love it for a few Times
Next thing Ya Know your the School Slut
Dont do it

You arent wanting to have sex for any of the right reasons. They are all WRONG!

Here are all the wrong reasons why you shouldnt *we have been going out for about 2 weeks now , although have been out before for about 2 months but just 'took a break'.*
*he wants to have sex with me.*
*he has cheated on me*
*I dont know if I am ready or not*
* I am not sure if he is using me*
* dont want it to be one of those things where he breaks up with me afterwards, because 'there is nothing left to wait for*
*I dont want him to get bored with me if I dont*

^^That should all be enough to tell you NOT to! I found this and it tells why a girl wants to have sex with her boyfriend. Heres # 8 which fits your situation
8. My boyfriend will break up with me if I don’t.
Breaking up is a possibility whether you are having sex or not. Nothing outside of a faithful, committed marriage has promise. And think about it. If your boyfriend says you are special enough that he wants to share bodily fluids, shouldn’t he think you’re special no matter what? Is a guy worth having if he threatens to move on because you won’t take physical risks with him? There are a lot of great guys out there who won’t put that kind of pressure on you. There are some very responsible guys who won’t get you drunk so that your defenses are down, giving you an excuse to have sex. (FYI - More than a third of sexually active young people report that alcohol or drugs have influenced their decisions about sex.)3 There are guys who will agree with and support your decision to save sex for marriage, guys who will respect you, now and in the morning. Hold out for one of those guys. They do exist!

And here is another article I send girls in your situation
Bad Reasons for sex too soon
· A need for sex.
· You want the person to love you.
· Social pressure to perform.
· Nothing more to talk about.
· Boredom.
· A curiosity to find out if there's any chemistry.
· You want to make someone else jealous.
· To persuade your partner to leave his or her current partner.
· You're challenging a dare.
· An attempt to solidify the relationship.

My thoughts are that he is only going to use you. If he truly loved you, first off you wouldnt have needed to take a break after only 2 mos. Secondly, he wouldnt have cheated on you. I dont believe he likes you in the right way. Hes clearly not thinking with the right part of his body!
I hope you make the right decision, because you will have to live with the consequences in then end. Always go with your gut feelings. If things just dont feel right, and you are confused, its always best to wait! No one has ever regretted waiting to have sex. Dont confuse sex with love, because sex is NOT love!
