A good tactic is Ploping Down to get Analingous'd or the Finger Self action done either in Seduction or Kneeling. If you have high strength, you can also engage in makeout during fullnelson.
There's also the good old fashion tactic of laying down, since a lot of enemies will happily sit on your face. Hit the Deck is massively useful if you want to enjoy some 69 or getting wrestled.
For topping, your best bet is making out or having them grind you mid-wrestle. Finger Self can work too, but for getting erect without high amounts of lust getting face sat without being 69'd is a risk you can take. Keep them struggled enough so you can break free. But some will just fuck your mouth then.
