Fruity thing with desire to get laid regularly outside (6)
I believe the answer is:
litchi
'fruity thing' is the definition.
(litchi is a kind of fruit)
'get laid regularly outside' is the wordplay.
'get' becomes 'itch' (I am not sure about this - if you are sure you should believe this answer much more).
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'outside' indicates putting letters inside.
The alternate letters of 'laid' are 'li'.
'itch' placed into 'li' is 'LITCHI'.
'with desire to' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for litchi that I've seen before include "piece of fruit" , "Asian tree" , "Edible Chinese fruit" , "Chinese tree; its fruit" .)
