I need info from people who have stretched lips

I have been considering stretching my labret and my medusa lip studs . I am aware about how to stretch lobe but I do not believe it stretches the same as lip tissue. I am really just looking for information from people who have personally done it . I enjoy everything about stretching and have large ears and would like to expand my stretching expirience. I would like to kn about jewelry you wear , any problems with saliva coming through or if wood or something would be better to control that if it is a problem . I don't want to go very big just to a 4 or a 2
