I found a solution. Thanks for your time :D !

I just put small perimeters and external perimeters at the same speed and VOILA. Bulge issue fixed for me.

I looked for the differences between my settings on S3D and prusaslicer and the only differences were this: There are not as many speed settings on S3D. The speed is almost fixed (only outside and inside speed but not "small perimeter or something")

Ok. You may also try pressure equalizer feature (it can gradually slow down the speed of the external perimeter to the same speed as external perimeter).
