Wife-swap and make love with Romeo – one goes both ways (5,4)

'both ways' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'wife-swap and make love with romeo one' is the wordplay.
I cannot quite see how this works, but
'wife' could be 'w' (abbreviation) and 'w' is found in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
'make' could be 'do' (do can mean to make or prepare) and 'do' is present in the answer.
'love' could be 'o' (love means zero in tennis) and 'o' is present in the answer.
'romeo' could be 'r' (phonetic alphabet: alpha, bravo, charlie etc.) and 'r' is found in the answer.
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
This may be the basis of the clue (or it may be nonsense).

'goes' acts as a link.
