2.5 years? how does it matter?
well i have been married for little over 3 years and for us sex is as essential ingredient as other things/aspects in married life.
I second that, indeed it is over rated unless you are a pornstar.
Emotional bond(Which is comprised by factors like trust,understanding and co-operation etc) matters the most.
this is very wrong perception that sex is only for pornstars or only they enjoy it most. actually its other way around, its their profession and they have to perform according to commands behind the camera, now where's the fun in that ?
