Remedy them... Wear ankle socks, Swim (the pressure will relieve some tactile sensitivity...) force yourself to put your chair off centre for a week as a challenge ec... If you do not feel you can self-motivate in this way, and the habits are encroaching on your quality of life i.e. Noticably last to sit down or leave class because of straightening chair to quell obsessive thought, then CBT may help to adapt the behaviour, though other sufferers and you yourself have the best solutions for beating OCD traits.
Ps I too had alot of pure compulsions, things just had to be a certain way, like the arrangement of my room, hoarding ec. OCD had thoughts attatched that would only budge if the ritual was exact i.e. Have to re-read this 64 times, squinting at each punctuation mark, or parents will know I do not understand, be distressed and punish. Perhaps your traits are ASD related, stuborn symmetry compulsions and tactile issues, if obsessions are involved, address them, don't let them build up. Take care.
