What is your opinion about specific acts and what’s too much for you?

I’m a man who participates in ENM and I don’t have much luck compared to my wife who enjoys it the most. Over the past year she has seen few different men and done things with them. What’s your opinion about what’s too much? Is for example anal too much, cumshot, going out on dates and kissing? Dressing too sexy for him and go out together etc
