S&M
It’s a pretty wide subject. People have written books on it! From a mild spanking to crucifixion we cant really cover it all here, so we’ll just cherry pick and hope you will forgive. Good rule. Negotiate. Tell him what you want and agree limits.
If the two of you are getting into a scene where “please stop, no no, don’t” is actually part of the routine then before you start agree an unconnected code or safe word like “Toyota” or “tomato” which actually means STOP!
If you are interested in S&M but have never done anything about it, how about starting out with a bit of verbal? Very popular and can be a real turn on whether giving or receiving.
Possibly best not to go straight to branding with a hot iron first time out of the stalls but then having said that you might well know exactly what you want.
But how safe is it?
Generally speaking S&M is very low risk for passing on HIV or other infections, though it would depend upon what you were doing exactly. For transmission to occur, infected blood or semen would have to enter the bloodstream of another partner - most likely through an open wound. Therefore if you were involved in S&M that resulted in bleeding with one or more partners, and/or if one partners had cum, the possibility of HIV being passed on would increase.
However, providing there are no open wounds there’s not a lot to worry about.
