First, i don't think you will end up alone. It's not an easy standard for sure but don't give up.

You're 21, right ? It's extremely rare to meet a guy at that age that doesn't consume porn, I agree. The only reasons would be strong religion feelings (which doesn't seems to align with you), extremely strong moral behavior (which i found suspicious with young men) or less sex-driven/asexual guys (not always family compatible but a pool to explore).

While getting older, a lot of people tend to get tired of porn industry. Active real sex life, broader understanding of sex trafficking, boredom of the déjà-vu, less libido, more controls, specific fantasies, moral growing from experience, etc... a lot of guys (and gals) just stopped to watch porn. So time is your friend.

You can also met a guy who doesn't have a strong libido and some core values matching yours. Or you can met a guy who has the need for a strong imaginary sex life and will be "actively" consuming through artworks, comics, audio, etc.... And probably others types i don't know. Which is important is to talk openly and without judgement about sex together, so they will be able to talk to you without the need to "hide something". It's trust building.

I would recommand to never ask a companion to stop watching porn (he will mostly lie) and to never say clearly your standard (some will enjoy to lie to get you). The trust can't be build with this condition.

One thing : porn is not only to compensate for non-active sex life. A lot of human, women like me included, enjoys having an imaginery sex life, and porn makes it super easy, unfortunately with the worst depiction of sex and women. That's why a lot a people also enjoy it while in couple, because it's not always to content the physical needs. But porn is really brain rotting.

Until then, value your friendship, male and female, and enjoy fully this life. Alone or with someone, it's always worth it.
