I believe the answer is:

be my guest

I'm a little stuck... Click here to teach me more about this clue!

'come and' is the definition.
I can't tell whether this defines the answer.

'stay with me and do what you like' is the wordplay.
I cannot really understand how this works, but
'stay' could be 'be' (stay can mean to continue to be a certain way) and 'be' is located in the answer.
'you' could be 'u' (commonly used in online communication) and 'u' is located in the answer.
'like' could be 'y' (similar in meaning) and 'y' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
