Hi and welcome to the forum. I suffered with this a lot. I had never had an orgasm ever and I was scared of what would happen because TV shows and movies make it look like this intense and big thing. I finally did it by accident and I thought “oh wow what was I scared about?” Now I have atleast a few orgasms every day or two. I suggest taking it slow and try to do it by yourself first.
It is quite a common condition. If you have been under stress lately that can cause it, there are a few other reasons that can cause the anxiety such lack of confidence during sex, past sexual trauma.
Not exactly the same but I tend to get it during sex. If there’s pressure for me to hurry up or if there’s something I want but feel nervous to ask. It’ll take me ages to orgasm if some of these things happen. I started setting an intention and really setting a game plan to be honest. Doesn’t happen as much anymore. Relax, go with the flow, but have an intention set.
Not strictly though I tend to kind of reserve myself and not let it happen as loudly and as naturally as I should when it does happen. Perhaps that’s just spending too long being used to having people I’d disturb.
