Is it normal i see every woman as a threat?

Exactly. If every man left their wife just for a bigger pair of boobs or nice legs, NO ONE would stay together. As cheesey as it is to say he likes you for what's on the inside, and clearly what's on the outside too. You should have nothing to be worried about.

You're just insecure. People are allowed to find more than one person sexy. That doesn't mean they want a relationship with them.

I think you should grow up and act like an adult, not a spoiled child.
This attitude obviously makes you miserable and will in time drive a wedge between you and whoever you are with.
It is extremely destructive to relationships to be excessively jealous and as an adult you should be able to rise above such petty feelings.

I wish I could say with confidence that this isn't normal, but it's obviously not healthy.

It's normal if you're insecure or envious, I think a lot of people have felt it before. However if you act on it, it can harm your relationship. My boyfriend has been honest he has those moments and I must admit it annoys me whenever he mentions it, but I'm also very grateful he doesn't act on it, it would make me feel he doesn't trust me and wants to restrain me.

I'd never leave him for a more handsome guy, I wouldn't even want him to be more handsome, he's the one I fell in love with and it's very important for me if wants to change anything it's for himself, not me.

If your boyfriend is a keeper he'll feel the same way about you.

Thats stupid.

I don't think that this is something you should worry yourself with as lots of women with partners get envious of other women, especially if their guy has had something to do with them previously, looks at them or even shows some sign of visual, verbal or mental interaction with or about the girl! I would suggest though because of photos or TV don't get jealous or he might not want to be with you because he may think other things like wow she's controlling etc. If you can I'd recommend you to go and see a local psychiatrist or similar person about this issue and if your really worried about it ask them if they can help you reduce the amount of rage and aggression you show to other women! The only thing that makes you not like something as howaminotmyself has said is insecurity because you don't think you have those things such as, as you say "huge knockers" and think to yourself, unless he's a sex crazed freak why would he be with you if he didn't think he couldn't go out without saying someone else is hot? He wouldn't be with you if he didn't have feelings for you, unless like I said he's sex crazed! Good luck :)

I think it's normal. I feel the exact same way. There's actually alot of things I won't watch with my boyfriend because of the women on it.

Because they are!

It's normal, though maybe not to that extent. It's nothing to be ashamed of, though. However, you should really seek professional help so it isn't this way your entire life. I'm the same way. I don't think I'm ugly or have an awful personality, but I'm always afraid that my boyfriends will want someone else. It's just insecurity. For example, I'm insecure because I have ALWAYS (and I mean that literally) ended up being the dumpee in the past. Also, I just feel there are so many better options out there. I know it sucks, and I feel for you.

Its normal but its not healthy. Jealousy and lack of trust are the reasons why most relationship fall apart. You wouldn't see a long healthy committed relationship be the way that it is if it had issues that you are having. Trust your boyfriend and stop being jealous because if you truly believe that your bf would leave you for a girl with bigger boobs or blonder hair or something like that then obviously you shouldn't be with him. If you think you need to babysit your bf so he won't cheat on you then that's a problem and your relationship wont survive if thats the case. But if you think that your just being insecure them learn how to cope with these feelings. You need to love yourself before you can expect someone to love you becuz if you don't even love you how do you expect anyone else to? Remember he picked you for a reason. Love is about trust you need that if you want your relationship to last because eventually he will get sick of someone always putting herself down and not trusting him and will find someone who does.You should be able to trust him talking to a pretty girl with out you acting like a jealous freak.

Who is a guy usually with?

Availability is everything. Given a fingertip hold of a chance, most guys cheat. Unless they're still satisfied from the last session with their current girl (or boy).

There are, of course, those guys that don't have the energy to cheat.

It's normal to be insecure. We all have good reason. The only questions is whether you let it get to you or not.

Give him a chance. And relax.

You should go and talk to him if you fell like he is attracted to other women.
