"Head"

 Nearly all men enjoy,
 happy to accept
 Most women relish it
 if their partner is adept
 
 Regarding those who want,
 with a desire to receive
 There are some reluctant
 to share, satisfy or relieve
 
 This behavior, for many,
 is difficult to condone
 They never really ponder
 why the selfish are alone
 
 So, if you choose not to give
 'Recipient only' is your stand
 You may find yourself lonely
 You better have a good hand
