Given how dynamic the interplay of systems involved in creating one’s experience of somatosensory perception is, as well as the rich neurobiological of individuals, I would say the answer to your question depends on the ‘we’ in question, as well as what might constitute a discernable difference in experience across the two sides of the body.
That being said, when it comes to our experience of our somatosensory perception we have a few key players (notably the thalamus and corpus callosum) who help integrate laterialized processing in advance of rendering to our consciousness the feeling of a unified somatic whole. If those players are compromised, their ability to stitch together the output of laterialized processing is also compromised.
I suggest checking out Coghill et all 2001 for an overview of the literature, as well as the literature on corpus callosum lesions, thalamic lesions, and case studies from Dejerine–Roussy syndrome.
