Any unsolicited photos sent my way where someone is nude is going to elicit a a very negative response from me. I've never yet encountered an actual woman that thought sending unsolicited nudes was a good idea, but I'm not going to say it's impossible for women out there like that to exist. The only unsolicited nudes I've received were from men who either were fucking idiots and thought they would magically get a positive response, or men who were entitled assholes who knew and didn't care that they would get a negative response, they just wanted to flash their dick.
I don't give a fuck about "societal pressure" as far as my sexual/personal life. It's my life, no one is being hurt by it, and my sweetie is very much a happy consenting adult. Hell, in general I don't give a fuck about "societal pressure" for anything, but I do try to live my life like a decent human. I'm quite comfortable saying I was a slut for a while. I was quite promiscuous but no one was being hurt by it and I feel zero guilt or badness of any sort about it. Safe sex practices and everyone knew they weren't my special sweetie/that I was seeing other people. More often than not, they were fucking people besides me. I've done paid adult cam work, I've hung out 95% nude at an erotic art festival, gotten kicked out of a shopping center because my outfit that covered more than a swimsuit was apparently too scandalous for some stick in the mud person, etc. Societal pressure can kiss my ass. A stranger's unsolicited disembodied penis photo does less than nothing for me.
I watch porn now and then and I like my sweetie's genitals. That's the full extent of caring about anyone else on this planet's genitals that I have, and the porn watching is infrequent. I don't get off on/care about the genitals of the actors in porn, though. There just happen to be genitals in porn, because, well, porn.
I'm extremely visual, but genitals aren't what do it for me. Someone I already find attractive with beads of water on their skin when they've just stepped out of the shower? Yes, please. Someone I already find attractive putting on a sexy display of some sort just for me? Yes, please. Watching someone I already find attractive getting dressed or undressed? Yes, please. Seeing bite marks or claw marks that I left on a lover? Yes, please. Especially striking eyes or a really outstanding smile, even on a stranger? Yes, please, at the least color me intrigued.
