It is important in web cam industry to set yourself some limits, some things that you can do and other you should not.
If you have never been asked by anyone in the private shows about becoming a model, than it is most likely you will be asked at some point and you need to treat those matters by showing kindness to the client.
Don’t you ever eat in front of the cam unless you are being asked to do so. It looks really gross and unprofessionally. Don’t ever beg for anything, only dogs beg!
Sometimes it may sound tempting, but you should never meet the guys you are working for. Shitty things could happen, you can not ever know what the guy has in its mind.
