Ngl, I've had sex with female friends just because they were horny and wanted something uncomplicated from someone they knew would respect boundaries. Most often, that was going down on them, which was fine by me since I always found that to be fun. Sometimes they'd reciprocate, or return the favor later on. Sometimes not, and that was fine too.
If I was bi or gay, I'm fairly sure I'd at least be willing to give hand jobs to bros.
Not all the time, every time, but at that same level of occasional where if the need is strong, but opportunity absent, why not? Doesn't hurt anyone, and as long as everyone involved is on the same page it won't.
Since Im polyamorous, thats not an issue for me or my partners, every one of us have done that at some point. Though for monoamorous people that is probably kind of insulting and problematic.
Yes even with exactly those words, which is a little funny :D
