I had a very prudish upbringing- no sex before marriage. Let alone all the other acts people get up to. It did make me feel pretty different when I was young.
Ultimately though, you have choices to make. Do you want to be in a relationship even? If so, it's going to be about finding someone who has similar values to you. I'm sure there must be some out there- even if they are rarer. But, it's fine to stand by your values. Of course, the frustration is, it may be much more difficult.
When it comes to other people. I can understand why this upsets you. An action you see as demeaning and humiliating has pretty much become normalised. It's also troubling to me that violence against women seems to be rife and I think the media we are exposed to only heightens this.
However, I also understand people who want to engage in these sorts of activities and, don't find them humiliating. Sexuality is complex. We all find different things appealing. They also may not enjoy being told that they are being humiliated if they don't feel it personally. It feels as if you might be claiming that they are 'letting the side down' if they perform these acts because you find them demeaning to women.
As another example- take mini skirts. I don't massively like the idea of guys lusting all over women. I don't like the notion of women as sex objects or, a collection of holes. I find that demeaning and I think certain clothes it has become popular to wear encourage those thoughts. I also don't really like femme fatale type women who use their sexuality to manipulate men. Some of this I'll openly admit is envy though! I simply don't have the figure to do all that!
Simultaneously though, I can't expect all women to stop wearing mini skirts! Some enjoy it. Some find it empowering or whatever. Some men even enjoy it. Fine- it's up to them. Do all women who wear a mini skirt end up getting raped? No. Do all people who give blow jobs suffer in abusive relationships? No. Do you have to engage in sexual acts or wear clothes you don't want to? No. If you are around people who pressure you to do those things, my advice would be to get away from them!
When I went to college, it became obvious most of my friends had had sex. I mentioned something to my Grandma in course of conversation and she said: 'They may be your friend but, they're going to hell!' By then, I must have been questioning religion because, I found that ridiculous!
Ultimately, you have to decide though. If this act is so abhorrent and monstrous to you- either you make it clear to friends you don't want to discuss sexual acts with them. Or, if it's so extreme, I suppose you'll have to avoid them all together.
Sorry. I remember now that this is a vent, rather than a discussion but ultimately- this will keep eating you up unless you find ways of mitigating it.
Personally, I came to the conclusion that I still liked my friends. Whether they chose to have sex or not. It was their choice and, it should be their choice. I could still follow my own beliefs. Being decent people, they didn't take the piss out of me for being a prude!
If you truly feel like you can't function around people who do these sorts of acts though- have you considered trying to find groups of people who likely won't? Religious groups spring to mind.
Ultimately though, you can't keep calling something someone chooses to do disgusting and expect them to come around to your way of thinking. People take offense at effectively labelled perverted.
But sure, as an overall idea, I suspect many of us can relate to being a particular person or holding views that don't seemingly gel with the rest of society. Plus, a lot of people here feel marginalised or discriminated against in one way or another. Those feelings can absolutely be valid I think.
I also think it's a reasonable question to pose- Do certain sexual acts portrayed in the media and done in real life encourage abuse towards women? In some cases, I imagine- yes.
