show her your body...make out with her and feel her body in a more than sexual way.
put a finger in her butt
its dif for every one but kissing on the neck and lil things like that will do it
When you and your boyfriend/girlfriend are snogging, touching them is OK if they are cool with it.
It should happen if your relationship works well
Rub the back of his neck hard.
You keep kissing pationatly until she looks. Give it some tongue to! maybe put your hands through her hair.
Unfortunately it sounds like you're not completely over your ex or at least still tie in those feelings with kissing. How about you do a bunch of new stuff you haven't done before/in a while with this new girlfriend, that should help you associate all the things you might do with a girlfriend with this girlfriend.
dump her... whats the use of having a girlfriend if you cant show her off by kissing her in public!
cheek.
Come on its kissing your girlfriend
It depends, if the relationship has just started, then hug him while kissing him.
Just don't do it. Your girlfriend should actually find it hot that she turns you on that much. And you can't do much about it anyway, because to stop it you would need to focus and your girlfriend would most likely prefer you to focus on kissing. If you still want to... the best you can do in that situation is think about something else like maths equations or a song or anything. That is true, I recently read one of those moral type books, regarding kissing, in extreme cases, you must not kiss your girlfriend until she is your wife, or if you must it should be no more that a quick kiss on the cheeks, that way you should not get a erection. But the question is about stopping a erection while kissing your girlfriend. I found that really impossible while I was courting (dating) my girlfriend, wife to be, once I started kissing her, I just could not let go, of course I got a automatic erection which always stayed up until the kiss was over. Unless you are very religious, it does not really matter, of course you need not kiss her at all, but then she might wonder if you love her, I never really worried about having continuous erections when I was dating, I just accepted that as one of the things you get when kissing.
lie to him that u saw his girlfriend kissing another guy.
