How To Get Rid Of Constipation?

Hello, well here is the thing, my doctor said they didn t think anything was wrong. My bowel movements have been pretty weird lately, short and thin stools, I have been exercising, eating healthier(A lot of fiber and such), Last time I performed anal sex was in November, but it started acting weird during mid February. so my partner and I haven t had sex since then. It comes and goes, but lately it just stays When I strain my anus swells up, but it immediately goes down after defecating. There is no blood or anything that would sound severe. If I were to rub my finger it feels rough or dry, I guess. I would think Constipation is the most occurring symptom and thin, short, soft stools. Nothing that affects my body anywhere else. What do you think, sir? Thank you in advance!
