tight stomach???

hii!! i (19f) have been trying orgasm for a while now but i cant ever seem to approach a climax,,,, masturbation feels good but i give up eventually because nothing is happening 🫩 after i stop though, my stomach feels tight and takes a while to return back, i can feel it relaxing itself (lmao sorry this is a terrible explanation). i also experience a strained stream when i try to pee after 🥲 just wondering if anyone is in the same boat and if anything has worked for them
