Two years back I got married. My problem is about sex. I want to know, after how much time physical relation should be done? My husband gives a big gap for it like 3 or 4 months and some time more than this. So I want to know that after 2 years this gap is ok??

Frequency of sex varies according to individual and his/her age. There are other factors too. Almost all surveys done regarding frequency, concludes that after two years of married life majority of couples do it some where between once a day to thrice a week. It may vary beyond these figures but once in 3-4 months is too low frequency.
