How much `honesty' and `sincerity' matter in relationships?

^ no no and still no ... you should not lie - dadu's advise!

but whateva - if you wanna have an affair - that's your choice - none of my bizzzz

...but tell me - guys who have affairs and MUST avoid honesty wid your partner - do you have an affair because you are not satisfied with your partner? or you just love hopping around - and how many partners at a time?
