You're picking one part of a very elaborate post, reacting to that because you disagree, and are expecting the rest of the post with very valid concerns to thereby go away.
Listen, I understand that my reply may not be what you were hoping for on this forum. You posted in outrage over your husbands online business and are now being confronted with having to reflect on yourself. I understand that's confronting and uncomfortable.
However, my motivating to make my post wasn't to create discomfort, but to stimulate critical thinking and growth. Because as a plus size mother myself, it makes me sad that women who look just like me go through life hating themselves and their bodies. And I genuinely think you deserve better than to feel that way about yourself.
So I'm going to reply again and stand by my previous posts.
I did not say "everyone should be naked with their partner every time they have sex because that is normal"
I said "Normal intimacy is the kind that doesn't get hindered by your own personaly psychological issues"
What that means is having the freedom to choose. Not to be restricted by your insecurities, your inhibitions, your anxiety.
Being able to choose to stay fully dressed because you find it arousing is a whole different thing to staying dressed because you're ashamed of your body. Having a partner who's turned on by seeing you half dressed and choosing to go along with that, is completely different from lying to yourself and pretending your partner shouldn't care about seeing you naked and should be content either way. You are trying to convince yourself that nudity is not important to a healthy sex life and that's just absurd. A hundred thousand years of evolution and all of scientific research disagrees with you.
What's happening now is that your own insecurities are dictating what can and can't happen in your sex life. You have lost the freedom to choose, because your self esteem issues have become a prison for your intimate life with your husband.
The day you wake up and feel that you are free to stay dressed or get undressed, and the choice is determined by what you find arousing or what your husband finds arousing, that's when intimacy becomes normal again.
Restricting yourself and your husband because of your insecurities, that's what's not normal.
So again, stop fixating on whether it can be normal to have sex dressed or in the dark. It can be, when that's the thing that arouses you. It's completely abnormal to do that only because you don't want to face your insecurities. And it's also completely unfair to unilaterally decide that your sex life gets reduced to this, give your husband no say in this at all, and then get upset when he looks at pictures online.
