Masturbation during sex

Here's something I've been wondering about.

Many of the women I've had sex with have expressed how they like to watch a man masturbate - and in many of my past encounters I've been only too happy to oblige. All good fun being watched and watching - and I know that there are men who like to watch their partner too.

But if masturbation is performed as part of a real-life sexual encounter, does it count as a reset or is it just a harmless fetish?

I haven't had sex since before starting this reboot, but it'd be interesting to get some other people's perspectives.

 

Oh I very much know sex is an addiction - for me porn is just one aspect of that.

And as much as sex should be spontaneous, natural and non-mechanical, there are still tastes that get expressed during the act ... whether that be fellatio, mutual masturbation, anal or whatever.

I don't think masturbating in front of a partner is inherently wrong, but I do wonder whether the actual strokes, the direction of movement, the position and the feeling will be enough to trigger someone into more of the same once that partner isn't there.
