okay first of all, i’m not an expert or a scientist, but one thing that i can tell you for sure is to not believe everything you see in porn. most of time those actions and reactions you see are exaggerated for the sake of entertainment. porns are not documentaries; their purpose is to arouse people, not to inform. that’s the most important thing you need to keep in mind. and second, people experience orgasm differently; what others experience might not be what you experience. so please know that you’re not wrong or broken for not having the same reaction as those you see. now onto the topic of whether you really experience orgasm, i cannot give you an answer too. but from my personal experience, the pleasure is fleeting too when it comes to clitoris stimulation. it’ll last for only a bit and then everything seems to go back to normal, so now you have at least one friend who’s the same as you. i suggest you not to worry about it too much, as long as you feel good, that is all that matters. you can experiment in the future to see what other things give you pleasure, you might find something that makes you feel mind blown, you might find something that’s not. the most important thing is to explore with caution and safety. and i hope my answer is somewhat useful or at least helps put your mind at ease😊
