I’d say it is

If you’re the wearer - the ball gag adjustable enough, not too tight, although it doesn’t have holes so it’s not exactly breathable, but since it’s not too tight you can still breathe around it. Or through your nose, duh

If you’re the receiver - it’s a small enough dildo to take anywhere, as long as the position is right. I personally think the best one is face-sitting for this dildo gag, but that would make it less beginner friendly because that squatting position is not ideal if you’re not feeling athletic at that moment.

But if we dabble into the level of mental play, I would say it’s a little bit more on the advanced side. The intricacy of power and domination play with this dildo gag is intense and not 100% made for beginners, at least for one reason, if not anything else - it’s the type of play that requires a safe word, and you cannot exactly use it with a ball gag in your mouth, can you? So please determine beforehand what your safe “gesture” or “move” will be if the submissive wants to tap out.

Otherwise, no notes, it’s a wonderfully mild ball gag
