That but also some men are capable of it and prefer not to. I've had clients who strangely were okay with everything BUT penetration and kissing because they felt that was cheating. Not sure where the logic is behind that lol but if it makes them feel better, that's alright. Some men also can't get used to condoms but still want to see SP, so they opt for sessions that include everything but penetration. The truth is that as SP we have to accommodate a wide variety of sessions within our boundaries.
Lol. This logic falls under the same logic of the restrictions I placed in my relationships when it came to 3somes. If they were never going to be willing for a MFM 3some, then penetration on her was not allowed.
We all 3 got to play freely, but his member was not going to be stuck inside someone else, if I was not going to get to feel someone else inside me as well. For me that would have been the unfair line that would make the relationship a sham, and an instant dealbreaker if he could be inside others, and I only ever feel him. F*CK THAT nonsense. He could only do to her what I could.
