Skype and video calling one's wife

Q: I am living in Saudi and I am from Pakistan. I often call my wife through imo or skype. Sometime I feel a lot of sex and often I see some sex urine from me not urine but like urine white colour. I am sure that all men have this kind of urine before sex or after seeing some sex or woman but my question is if that water or urine come out, can I do zikar? If not then what to do? I love zikr, istighfaar, etc, but that is a big problem for me.
