Took a seat with your lecherous man (5)
I believe the answer is:
satyr
'lecherous man' is the definition.
(I've seen this in another clue)
'took a seat with your' is the wordplay.
'took a seat' becomes 'sat' (I've seen this before).
'with' says to put letters next to each other.
'your' becomes 'yr' (shortened version of 'your' in eg textspeak).
'sat'+'yr'='SATYR'
(Other definitions for satyr that I've seen before include "oversexed fellow" , "Trays (anag.)" , "Sensualist" , "Greek sylvan deity" , "Part man, part goat" .)
