You might be able to push stuff aside with some effort, the question is whether it stays in the same location you push it to or 'flows' back. Even the air and your clothes would be an issue otherwise.
But chemical processes? If you get a spark to appear it will just hang there unless you move it around. That's also the reason why I mentioned needing or being to absorb nutrients in my first post, you would otherwise have a little issue with drinking and eating being impossible. If anything you trigger unfreezes to complete what you started you would be able to awaken other people too. If only something in your body will 'awaken' and otherwise will just be moved then the only way to use explosives would be to have them go off inside you, which might cut short the 20 years.
Bicycles should still work as long as friction works, but might be heavy as you have to push against the air too.
And yes, sex with hotties might also be less nice than what people are expecting. If you can move them unless it tries to return to the original location nothing would 'bounce back'.
If you need air, food and water and only your physical body moves you would suffocate soon, so you would need to either freeze time selectively or have a zone around you in which stuff is not frozen (or indeed have everything you trigger/touch unfreeze, which would most likely cause a chain reaction by the air you breathe out to unfreeze everything it touches, or cause you to suffocate the moment you stop moving around as the air pocket you are in fills with CO2 (good luck sleeping!)
If you don't need any sustenance and everything you touch won't provide you with more than normal (non-frozen) resistance you could do a lot though.
Oh, and I overthink stuff like this
