What are some example of mental compulsions? 
Most of my OCD themes have mostly mental compulsions, like ruminating, rationalizing, trying to solve the thought/come up with an answer, think about my past, self assurance. 
It’s been hard for me to identify my mental compulsions since they’re mental and not physical. 
My other compulsions like assurance seeking and such involve physical action, so I can stop those one quick, but my mental ones are harder. 

Do you guys experience these kind of mental compulsions too?

All of mine are mental! My easiest one to catch was rumination but I notice my self reassuring and problem solving ones were the hardest to combat, I am still working on self reassuring myself like disproving a thought at times. I think when you are in therapy or even practicing erp you can quickly notice habits that have become compulsive!
