Many women struggle to have one orgasm during sex.it’s estimated women orgasm between 46-50 percent of the time , let alone multiple which many women have never experienced - so I’m not sure why that makes us luckier . It’s definately trickier
I've not had many sexual partners, but I've only had one who couldn't seem to orgasm multiple times (and I think she had some 'issues', or just didn't like sex at all). Most seem to climax within 5 minutes of foreplay. Maybe I'm just good at giving, or picking women who climax easily, or maybe they've all ben faking it? Don't know why they would fake it multiple times though.
Anyway, I'm a man who suffers delayed ejaculation, and I know it upsets my partner a bit - she thinks it's her fault that I don't climax, or that I take a very long time to get there. Sometimes we have sex for ages before I get there, other times we both give up, exhausted from trying. I think it's mostly psychological for me, but I really don't know what's behind it. It never used to be a problem, but has slowly become more of an issue since my mid 30's (early 40's now).
I do have a couple of theories (which may or may not be of any significance for the OP). Firstly 'death grip' does not exist, at least not in the physical sense. If they've been wanking loads recently, then yes, that might make it harder during sex with a partner, but that's no different to if they'd just been having lots of sex too. To be a physical sensation thing, it would have to have been very recently, like right before your sex session started.
I have noticed that, that when I give my partner extended foreplay (which we both enjoy), that seems to make me take longer when we get to the main act. I'm not sure why exactly, maybe that my arousal has waned a bit after I've got so excited during the lengthy foreplay. It may be because the more foreplay we partake in, the wetter my partner gets, and when things are so wet there is zero friction from PiV, so the sensation (for me at least) is reduced to minimal or non existent. This may also be because my partner is rather loose (or perhaps I'm just not big enough for her), so the physical sensation of PiV is rather minimal for me, this is definitely more so than with previous partners, so it does seem to be an anatomical thing.
My partner is rather rough when she gives me a handjob during foreplay, and I think this does reduce cause a temporary loss in sensitivity - this is similar to what people on here keep calling 'death grip', but I think it only applies because it's immediately before PiV. She also likes PiV rather hard and fast right from the start, whereas I'm more used to building up from a slow start, so again, that might stifle the sensations further on.
One thing that really makes it worse is that when it's taking a long time, it puts pressure on me to hurry up, especially if I think my ex is starting to get fed up (understandable). It's unavoidable, but that just seems to make things even worse - the issue seems to become self perpetuating. I do think stopping for a break would help, but I also know that my partner probably wouldn't want to carry on again afterwards.
I don't know if the OP can relate to any of that, but it might be some food for thought?
