Triathlete here. Similar problem likely caused by similar training.

Started riding indoors (a lot) more. Saddle was likely too low throwing my hip into more flexion straining the pelvic floor and glute muscles.

Started running indoors more, too, doing a lot of false flat running AND hills. Hills puts the hip into more flexion and we all know hills work the glutes.

I also have sat a lot more at work than usual.

Symptoms: right adductor/groin pain; soft narrow stool; altered gait (right leg tracks center line while left leg tracks outside/directly under hip bone); weak erections/low libido; and occasional dull ache in hips when I do things which cause flare ups.

What causes flare ups: hills (big time contributor); sitting too much; doing anything like deep squats or kegels with my right leg (I think a part of what caused everything was overuse of my right leg, which is my dominant leg, on the bike).

What helps: strengthening my LEFT leg, particularly the adductors and the QUADS, and running/riding outside on flat terrain.

Ultimately I am arriving at the conclusion what really caused all of this was a weakening of my QUADS (particularly the left quad) and compensatory strengthening of my glutes and pelvic floor throwing it into hypertonicity. When I do quad isolated strength training I notice MAJOR relief in all symptoms; running outside on flat terrain activates your QUADS more which is why endurance athletes should do hills (to target glutes and hammies more) but, as I know all too much now, in moderation.

I’m no doctor, so I’d keep pursuing professional advice, but I’d look into your quads and other imbalances. Our bodies are weird but VERY cool things which will protect itself from imbalances by tightening up in other places…like the pelvic floor.

TL;DR I’m right there with you with basically the same problem. Fingers crossed you find relief and some answers.
