I’m not currently, those days are behind me. But I’ve done it in the past. Primarily for women whom id been friends with before, or in most cases fuck buddies with who got into a relationship with a man who wasn’t satiating them the way they wanted.
I only ever met one of the men personally, admittedly it was a pretty awkward situation. He seemed okay with it. I could tell it really wasn’t his idea, but he said he was on board. He never watched or wanted to be in the room, but his girlfriend would have me take POV pics of my cock in her hand, mouth and pussy. “For reference”
The other two, again were women that I knew and had been with before. I messaged their partners before doing anything to make sure everyone is on board. One of the guys was really into paying for us to go on dates. Like he was a really nice guy, and from what I could gather they had a pretty decent sex life, but he wasn’t very social so he’d pay for us to go on dates. Us having sex wasn’t a huge part of it, but the guys as totally fine with us doing it. The woman said that sometimes she just wanted a change of pace in the bedroom. He was a bit more gentle and borderline submissive but sometimes she wanted to be fucked into oblivion.
The other women was a similar situation except this guy apparently did have a really small penis and she wanted something more. So we’d hook up, it was almost transactional feeling. I was okay with that at the time, like just show up and fuck and leave.
