I mean, lips, tongue, breath against the skin. Especially in secondary erogenous zones like behind the ear, ear lobes and on the neck (look up a list, there are alot of them. Some are in very unexpected places like the small of the back).
Squeezing and groping also feels really good. I especially like groping hands on my bum and upper thighs.
I am also quite keen on a little gentle scratching and biting. But i know thats not everyone cup of tea.
Playing with ice is a classic trick too. (Make sure it melts slightly and goes past the sticking stage.).
Putting a ice chip in your mouth is the classic trick (especially for oral).
Hot wise you can do warm massage oils, massage candles, wax play (read the instructions and use only candle made especially for this purpose if you want to try it. They have a lower melting point).
Massage is a nice way to start a session though.
Also, if you like sensory play, a blindfold is a great option. Makes everything more intense. Doesnt have to be fancy, just scrounge an old silk scarf or tie you got for xmas and your set.
Also simple sensory toys like a feather or a silk scalf on the skin can be amazing (especially if your using a blindfold)
Toy wise bullet vibes are your friend. They small, easy to handle and good all over the body (but not anal safe, so if you’ll wand a separate anal toy if you’ll want to play back there).
They’re sold as a clit toy but well worth trying on a penis too as many of the guys on here are very keen on them.
The desire one is my fave. Very rumbly. Mantric also do a nice bullet vibe. The Glow up bullet is also a good budget option.
nipple suckers and nipple clamps are alot of fun as well. They give you sensation when on and also make the nipples more sensitive after youve removed them.
Clit balms are also fun. You can get warming and cooling ones. (This is my current fave)
They can be nice elsewhere as well, though you can also get specialist nipple balms too.
Edible body paints or food can also be good fun. Chances are Its going to be sticky whatever you pick, but fruit and chocolate sauce are good options.
Edging combined with some bondage is also very worth trying. The restricted movement makes it very intense.
welp, that was a longer list than expected. Hope some of them sound fun.
Having a wander through the forum is also a good idea as its an endless font of ideas. Ive just thrown a few together
