Longing to get into bed with extremely tactile vegetable (9)
I believe the answer is:
courgette
'vegetable' is the definition.
(I know that courgette is a type of vegetable)
'longing to get into bed with extremely tactile' is the wordplay.
'longing' becomes 'urge' (both can mean a desire).
'to get into' means one lot of letters goes inside another.
'bed' becomes 'cot' (cot is a kind of bed).
'with' is a charade indicator (letters next to each other).
'extremely' means to remove the middle letters (only the extremes of the word are used).
'tactile' with its middle removed is 'te'.
'urge' going inside 'cot' is 'courget'.
'courget'+'te'='COURGETTE'
(Other definitions for courgette that I've seen before include "Type of vegetable marrow" , "One of the vegetables" , "Zucchini is its American equivalent" , "Variety of marrow" , "Zuccini" .)
