text: I can only speak for myself here, but it actually a combination of a few things:\n\n1.  I love to have my wife lavish me with attention on occasion.  \n2.  While I really enjoy "regular" sex, while we're "involved" I want her to enjoy herself as well.  However, I can only focus well on one thing at a time.  If I am occupied with pleasing her I cannot focus on my pleasure and the experience sometimes leaves something to be desired.\n3.  I enjoy things a little "kinky" occasionally.  While "regular" sex is great, I like to have things spiced up from time to time.\n\nOral sex allows me to forget about focusing on her pleasure, and enjoy the experience for myself.  Since I can relax and not have to worry about her, the pleasure is increased in intensity and enjoyability.  It's also reassuring that she loves me enough want me to experience this level of pleasure.\n\nRest assured, I always take care of her afterward as my little way to say "thank you".
