I do like All of the above my gf loves to do everything pleasurable with only. It does excites me when she gives me a head and even breast-fuck and I know she likes for me to cum on her breast though that may get me to do more for her. My baby (1LovelyKinkyKitsune) knows how to give so much pleasure to her Daddy and I love everything she does for me and I would do the same for her. ;)
Blow job or tit job. Many woman don't work the hand job right for me and haven't had a foot job before.
Blowjob, both give and have.
Hand, tit, and foot jobs all nice, too, but are definitely tied for second after that one.
