I think physical connection is very important specially to our love ones, like me five months already that i cannot saw my wife and children because they live in the province where i came from, because of work i will sacrifice, I missed the care of my wife and the moments and time with my children, although we connected through facebook or with the use of cellphone but for me its lacking, i want physical connection or actual love and care, so that i will be happy and have satisfaction.
Thats why the long distance relationship doesnt mostly work at all because sometimes irrespective of the love and feelings that you may have for the opposite sex, physical intimacy is very important and when you dont get it it leads to cheating.
