So my girlfriend and I have a little problem with teeth, she says I'm too thick for her to open her mouth more, so her teeth scrape against me and bruise my penis a bit. Personally, I'm too scared to tell her, so I've just been giving her little tips to make it better, yet I'm not sure what to tell her to do. Anybody have any tips on how to prevent this, or tips on how to make a blowjay feel great that I can tell her? Anything appreciated, tips on deepthroat too.
