Is it normal that at 22 i am unable to get hard on without stimulation?

No, I'm afraid that's not really normal for a guy your age. A healthy twenty-two year old guy should be able to get an uncomfortably hard erection without any physical stimulation.

One well-known effect of porn is that, after a certain amount of exposure, we tend to become kinda numb to whatever particular type of porn we've been using. Back when porn was limited to magazines or 8mm films, everything available (with a few rare, extreme exceptions) was all what would be considered boringly vanilla these days. When I first watched a porn flick back in the seventies, anal was considered very kinky. These days, anal is virtually the minimum necessary for any porn video.

This numbing effect is why porn has had tended to get more and more extreme. Guys (and it is mainly guys) need something novel and weird to get it up and get off, and an attractive woman enthusiastically sucking a big dick just isn't enough for many guys.

Some other things for you to consider:

Are you on any medication? Some have side effects of reduced sex drive and impaired erectile response.

Are you regularly using any street drugs, or drinking a lot of alcohol? That can mess things up too.

How about what else is going on in your life? If you're under a lot of psychological stress or constantly distracted by repetitive thoughts, that can make it hard to get hard.

Another factor is that, once a guy experiences what he perceives to be erectile dysfunction, worrying about that happening again can make it more likely to happen.

Finally, you might think about your masturbation technique. If you train yourself to need very rough, aggressive stimulation, that can desensitise your penis to some extent.

Blow me.

Bullshit! It's perfectly normal to be able to get it up with manual stimulation only. Sure sometimes a guy can spring a bone with no stimulation but it's not a normal "all the time" thing.
