It's obious that if you c2c you're not satisfied with being only with your partner… you need to see, if not touch, other men/women/etc, to arouse yourself.
There are 2 things to keep in mind.

1. You are so insatiable that your partner is not enough: solution a) if you love him/her so much, show a minimum of self-control... are you a teen in full puberty? b) confess that you have a problem (hypersexuality, nymphomany for women and satyriasis for men) and see with him/her what you can do... maybe you both can enjoy this freedom or maybe you two can use the cam together.
2. You are not really in love with your partner: a) pretend to continue like if you love him/her, your partner will find it soon or later, your relationship will be in crysis, but it was from the beginning, b) speak with him/her about this, talk about the strenght of your bond, let's see if there is a solution for not losing it or if you can be simply "friend" or "fuckfriends" and not a real couple where some degree of devotion is needed. Or maybe go back one step, try the point 1).b) and see if your relationship will improve sharing something you like very much and maybe he/she may like too...

pretty much this
