Is it normal that i always cheat on boyfriends, no matter how much i like them?

Maybe an alternative lifestyle is better suited to you. Such as an open relationship, or swinging.

Don't be that person. You need to nip this in the bud while you are young. You don't want this destructive behavior following you into your 20s, 30s, and the rest of your life. If you literally can't stop yourself from cheating, stay single and get therapy until you can get it under control.

Cheaters are their own worst enemy.

You've got to realise that you cannot have both. You can't have a steady partner and the enjoy the constant positive reinforcement of dates and sex with other people. It's not acceptable or condonable.

Maybe you find it hard to say no to people. So practice saying no. Practice rejecting people. After doing it a few times, it becomes easy not scary. It's empowering to assert your boundaries; it's not a burden.

If you genuinely want to control your behaviour but just can't - and if you don't know why you can't control it - I would recommend seeing a therapist. Compulsive, destructive behaviour is not normal, and seeing a therapist may help with it. Maybe this problem will get better as you mature, but I wouldn't take that chance. Until you get this problem solved, I think you should avoid all relationships, dates and casual sex. You might find that being single does you good.

I glad no one has slated you for this, because you clearly have a problem. Or, do you really have a problem? Many people these days, like me, don't believe in marriage or long term serious relationships. It's archaic. Like others have suggested, have you considered taking part in open relationships and such?
It all depends on what YOU truly want. Do you want a relationship and stay faithful within it? Because then we do have a problem. Do you want to be single so you can enjoy being who you want to with without commitment? Do you want to try open relationships?
Most importantly, you're 18. You are way too young to even be thinking about marriage and serious relationships. It's 2014; marriage and serious relationships isn't everyone's priority and dreams anymore. I know personally, I would take a successful career over being anyones wife anyday. And trust me, you're 18, things will calm down in the next couple of years. When I was 18, I was bonking all over the place like a cheeky little naughty rabbit, didn't matter if I was in a relationship or not. But now, I can sustain faithful relationships. You grow up, experience new things, probably have a change in the way you see the world and what you believed to be, and you change as a person.

I've always been the same, everytime I'd be like this is the last time but then.....

is that you jessica? hahahahahahahahahahahahahahahahahahahahahahahahaha *dies alittle inside*

At your age, it's normal to be tempted and to have crushes on other people while in a relationship. You're young, and your hormones want you to sow your wild oats. But if you feel like you can't stop yourself from cheating with these other men, then there may be a problem. Do you have trouble with saying no to others, or making decisions? If you grew up with unusually strict parents, it may be that you're not used to having freedom to choose for yourself, so you struggle to commit to one guy.

I agree with the others that seeing a therapist and avoiding committed relationships would be wise for the time being. If you still want to date, keep it casual. It sounds like you have already taken positive steps by recognizing the problem, and cutting ties with the guy you cheated with. Awareness is the first step. Good luck!

When your young most break a lot of hearts

Maybe it's not temptation you need to say no to, it's a relationship...especially now entering college. Definitely time to see what's out there without any ties. I'm not saying to whore out but you know :). One day it'll get old or you'll find "the one" or maybe not! At least you won't feel guilty. Stay single for a while and have fun. My college days are over and now I'm just a boring wife :)

I get too tempted as well which is why I am remaining single.

Maybe you're a sex addict? If you can't control it you may very well be addicted to sex.

I always do to ever since I was 12 or 13 I've always had at least 4 dicks in my mouth and my pussy on a regular basis

Because you're a woman and women are confused by their nature.

You don't need to be told it's wrong, so you shouldn't need to be told it's not normal behaviour. Stop thinking with your vagina.

What do you expect us to say?
