I have a a 93 honda civic that will start run and drive but wont go into 1st or
 

reverse without turning off? My 93 hond civic ex stickshift one day started to shift into gears really roughly, then all of a sudden wouldn't go into first. Later on I found out that it will start the car in first and would shift through the gears, but can't go into first or reverse when it is running. It still goes through ALL the gears really rough, but first and reverse are the ones it won't go into without the car being off. I don't know anything about cars, so I just wanna know how to fix this problem

It is a clutch issue, either the clutch master or slave cylinders are failing (replace and bleed) (or replace cable if bad and has cable) or the clutch disk itself is failing. Replace with pressure plate, and throw out bearing. $$$
