I was kissing my g/f and her mouth was pretty open, so I started to put my tongue in her mouth. She pulled away and said "ew you put you tongue in my mouth". It was just sort of embarrasing. But, it was quickly forgoten and she gave me a quick kiss before she left.
I'm not going to try that again. Is there something I should do differently next time. Or does anyone have any advice or any opinions on this lol.
