The first is prostate massage.  One gal just went ahead without even asking and started in with it during a hand job at an MP.  She was very dominant too, so I sort of just took it but she was also very good and in a short while I was getting into it.

There are a very limited number of gals who are willing to offer that, let alone are good at it, but when I find one like that I usually take them up on it.

The other is lashing or other forms of inflicted pain.  I would have never thought it was my bag, but not I find it very erotic and enjoyable with the right provider.

I could mention snow-balling as well except I got inducted into that club by a civie, not a provider.

I love being smacked every once in a while till I turn blue...  

Sometimes a woman who gets a lot more practice than either of us will ever get, from a wide range of partners, picks up a few skills that can create greater pleasure or add a bit of chemistry or whatever that you or I have never come across. So, when she's with you, she suggests that you do such and such and such, and shows you how she most likes such and such and such, and then you go away with another little tidbit of carnal knowledge that you can try out again the next time you play. You've just bettered your game by doing something new and different. Try it. It's fun.

What is tuma, pegging?

TUMA - Tongue Up My (John's) Ass

Doesn't that fall under the category of posting an ad?

On a couple of occasions providers started snaking tongues or fingers toward my poop chute during a session.  I quickly and politely let them know that was not on my "menu". Funniest was a lady who started lifting my legs as if to bend me in half so she could get at my starfish.  I let her know I appreciated the effort--and her strength--but that it was not my thing.  She was quite disappointed; she let me know she really loved doing it.   Glad she was a good sport--20 minutes later I was tapping her alternate entry and it was quite fun.

Encountered resistance because that's where I hid her engagement ring. Lol.

"She would go meet her (other) connection
At her feet was her footloose man..."

exploring, learning... so many other things as well, for me. Can't get that from the same vanilla everyday, everytime. I feel free to say no, but it's a privilege to be asked. Hopefully it sometimes works the same for the gals. I'm sure "pressure" to do something sucks either way.
