I have similar "tight" feeling and I´m 5 month post-op from PAI. However, the tight feeling was there from the start and it has faded a lot since from day 1. I think it has something to do with tissues healing and connecting together and everything just trying to adjust to new settings so to speak.
At first I was afraid that I was left too much erectile tissue, and yes that might be the cause, but it really doesn´t feel like that. It is different, tight, is the word and yes it is around clitoris.
Give it still some time, because I have steadily been getting better and better.
