Watching your guy jerk off?

Maybe it’s just me but I feel like most women now and days feel that it is okay for their S/O to jerk off or even find it a turn on. Am I the only one that finds it disgusting or even disrespectful? Nothing to do with insecurity I just feel like if your guy can’t get off on you and needs a video then is he really only about you ? 🤔🤔 Like with my boyfriend it’s a constant thing and behind me back and I don’t really know how to feel about it other than absolutely disgusted and disrespected.
