I have two partners: my husband and my FWB. I am very attracted to both, I climax much more quickly and with much less stimuli with my FWB. There’s nothing they do differently; I just react more. My concern is when talking about my experiences with my FWB with my husband, that he will become aware of the difference and feel discouraged/unattractive/like a bad lover. Might this difference just be New Relationship energy at work? Should I downplay this ease of orgasm when talking with my husband?
It might just be NRE at work. It could be that he has some little technique that he does differently that you don’t notice. It could be that the size, shape, angle, and/or texture of his fingers or other fun bits matches up with yours in just the right way. If you honestly can’t figure out what causes the difference, it’s fine to just chalk it up to the mysteries of the universe or the rich tapestry of life. (If you can figure out the difference, it’s okay to gently request or suggest to your husband that he try some things differently!)
Now, I don’t want to be someone who recommends that you lie by omission - but I’m not sure you need to tell your husband about this specific difference. I think there is a difference between deliberately misrepresenting something because you don’t want to deal with someone’s emotional response to it, and just not saying something that’s unnecessary and won’t make anyone feel good. There’s dishonesty, and there’s tact, is what I am saying.
If one of my partners took me out to an Italian place, and the next week another partner took me to another, less amazing Italian place, I probably wouldn’t say “you know, the place Quandon picked was a lot tastier than this,” because not everything that is true needs to be said. Next time the subject of picking a restaurant came up, I might recommend the other one, but without needing to say “it’s the one Branston took me to, and it’s way better.” That my partner took me out on a date and picked a place that serves my favorite type of food is a situation that doesn’t need to be critiqued, even if it’s imperfect.
If there was something seriously wrong with the food, or if we got there and I really hated the place he’d picked, of course I’d say something. A major project in most people’s lives is finding that sweet spot between “doormat” and “jerk.” But if the sex with your husband is fun, and he makes you come, even if he doesn’t do it with the laser precision of an android specifically and individually designed to pleasure you, it might not merit comment.
So unless you two have an agreement that requires a blow-by-blow of every sexual encounter, it’s probably not relevant. And even if you do talk about sex, unless you give specific timestamps of everyone’s actions and orgasms, this difference is probably not going to be super clear. It’s fun to talk about sex, sure, but you can mention something fun or interesting without going “oh, and also, he totally brings me to orgasm way easier than you!” If he asks, don’t lie, but there’s no real need to make that detail a part of the conversation.
