I don't feel normal about thinking this way so I wanted to know what it might be..
I dated a guy for 6 months, and had strong feelings for each other. I didn't care If he went to parties without me, I didn't care If he talked to girls,and I most definitely did not care if he masturbated to me, other girls or porn..

I have a different boyfriend now. We have been together for a year now, I ended up losing my virginity to him last Easter.. At the beginning of our relationship, I wouldn't have cared if masturbated to porn or me, I found it's dumb, but I laughed about it. A few months in he got drunk and cheated on me with another girl, but with a kiss. I was being dumb and cheated on him for “pay back" I don't think like that anymore, but, for some reason I am really jealous.

I don't like when he talks to girls, or drunk's without me because I have a feeling he Is going to do something stupid, or cheat on me.. About a week ago I found out through our whole relationship he has been masturbating to girls on YouTube, and porn all along.

I don't feel good enough anymore, I'm skinny, but I still don't feel sexy, I feel as If I gave him everything of me and It wasn't good enough because he has to masturbate to other girls, with bigger asses,and so on.. I'm also low on my confidence and I hate it.. Please read and answer?

May I have your ages, and the time you spent single between guys?

It appears that while you were comfortable with the first guy, you are not as comfortable with this one. Or maybe you still have a lot of baggage from the first guy, and still carry it to this relationship, or all of the above.

Maybe when the trust was broken, it makes you a bit sensitive now and gun shy that it will happen again. Interesting you chose a guy who was similar to the first one though in his sexual habits. Could it be his habits have you feeling left out?

Leave him, he's selfish, he just needs to listen to you, don't ask or talk to him, just leave him and get over him and go back with your ex that you had strong feeling for :) it's the best for you.

Ages are 16 going on 17

And the time you spent single between guys?

masturbating to girls on YouTube

Webcam sex? If so, leave him. The relationship is not special at all if he's that slutty. And girl, never feel insecure about your shape for a guy who doesn't know how to appreciate it. He's missing out, not you. If you want to lose some weight/gain some weight/look sexier, do it because YOU want to.

So you both are young and 16 17 year old boys do that. Is there a reason why you are still with him when you are feeling so uncomfortable? Have you talked to him about this?
There are a lot of emotions involved when you are having a sexual relationship with someone, especially for females, which is one of many reasons sex between teens is not such a good idea. Maybe he is more comfortable masturbating that having sex. It has nothing to do with you, but maybe he was not really ready for sex.
There is no reason for you to feel bad about yourself.

Jumping from guy to guy, especially wired ones and experimenting with sex, is not a great idea, and thinking sex is a real healthy love makes it worse.

You better rethink what you are doing, and who you are doing it to, and why you do what you do. Its is causing a lot of harm to you.
