@ouuji Everyone in the world is born different who's to say whats normal or not. stop stressing about small things when you let the water settle all things will become clear. Maybe if he did want to do those things you would react or maybe not. What I'm trying to say is you need to explore these things yourself, I do not posses your body and mind. Relationships also don't need to be sexual you can still love without that stuff.
Unless you have no teeth it is logical that it would painful. A baby forces the milk out by pushing the aeriola against the roof of its mouth, if there are teeth the nipple will be rubbed against them. And cheating on your wife and children will bring you all problems later. You can never rely on how 3rd parties will behave.
I can help you. What do you want to do? It's actually pretty simple once you get the hang of it. You can post announcements, message people, and chat in the public chat. Let me know if you need anything :)
