At another moment they might touch you in a way which is not exactly nice.
What do you do?
Do you share your feelings on the spot?
If it's something nice you can of course!
Now, when they are engaged into tantric play, partners might not be open to be educated on something they could do differently.
The best time to give your partner any feed back is the following day or even a couple of days later.
You can say things like:
"It really works for me when you touch me that way"
or
"That created some pain..."
or
"There is something I would like you to try next time if you are open for it..."
Your words will tell them exactly what works for you and what doesn't.
Sometimes, your partner might believe they are touching you in a way you like when in fact you can't stand it!
So to avoid confusion, tell them, share, offer feed back and be open to receive it as well.
It is one of the essential keys to keep on progressing together.
The key is to give feed back when your partner is open for it.
If what you have to say is challenging, warn them and ask them if it is a good moment.
Timing!
Positive feed back is of course much easier to give :)
