More sensual side introduced by son? That’s right (8)
I believe the answer is:
steamier
'more sensual' is the definition.
'side introduced by son? that's right' is the wordplay.
'side' becomes 'team' (I've seen this before**).
'introduced by' says to put letters next to each other.
'son?' becomes 's'.
'that's' becomes 'ie'.
'right' becomes 'r' (common abbreviation).
'team' after 's' is 'steam'.
'steam'+'ie'+'r'='STEAMIER'
(Other definitions for steamier that I've seen before include "more like a sauna" , "Comparatively hot and humid" .)
