Update: We are continuing our spanking exploration and came up with a couple of questions
Are there toys that should not be used on skinny people?
For guys, should they keep their legs close in case of hitting their balls?
What positions and how do you start the spanking? Like, do you have a roleplay scene?
Some guys like that 
Generally spanking, caning etc should only be done on well padded areas.
If she’s using the cane, paddle, crop, tawse or slapper then it’s on my bum or upper thighs. I definitely keep my legs closed
She only uses the whip on my back and only the flogger on my nipples and genitals.
Any toy can be used on any body. We’ve all got fleshy bits, some of just have extra fleshy bits.
As @rockstar said, some guys like being hit in the balls, also known as CBT (Cock & Ball Torture). Try it gently to begin with. If it’s a no go, tell your partner to close his legs.
Spanking can be done in numerous positions: bending over, kneeling on the bed/floor, leaning against the wall. It’s horses for courses, so you will have to explore and find what works for you both. You can get into it with roleplay, or you can spank for spanking’s sake, just make sure you stick to the fleshy bits 
Never really had the opportunity to try a roleplaying situation, I used to just always grab a cane or a flogger halfway through foreplay and go to town. I suppose it’s different for everyone though, experiment with the different scenarios and positions, see which one feels best for you! (:
I’d say all that depends on what floats your boat, see what works best for you 
Hey @Tenshadesandme great guide you have there. Do you find thin canes making you go crazy? It just stings and the pain stays with you for a while. Can it be used at the X spot too?
I think you might be missing the plot here. You can do what ever you want with another consenting adult. You want to “outlaw” hair brushes at spanking time? Done. You want balls protected from impact? Done. You want full scenarios built around each session with Thursday night script review before Friday performance? Done. Or you can do none of those things.
It all up to you and your partners(s) as long as everyone is consenting.
Hey @abbyk ,thank you for your kind words. Personally i much prefer thuddy pain (leather and suede floggers 
) over sharp pain like canes, so yes, caning does make make me go crazy, as you say. A good, hsavy impact play session stays with you fir a whil too, but the aches just ache different. A cane can be used on the sweet spot, but i’d only suggest it for the most masochistic. It can be quite excruciating for those who don’t like pain.
