I’m having trouble orgasming!!

I used to orgasm so easily and it used to be so satisfying 😩. But one day like idk a few months ago I like squirted and since then I haven’t been able to cum 🥺 like it takes an hour of getting ready (watching porn, rubbing softly over underwear etc) and then it takes a whole 30minutes plus to cum and it sucks. I just be tryna rub one out before I gts but it ends up taking a lot more time then it should.. why am I not able to orgasm as easily anymore ? Is there any new tricks ?
