Cant cum from sex if I wank 3+ days before is there something wrong with me?

I have found myself not able to cum from sex if I masturbate this would make sense if it was the same day but if I jurk off multiple days before say I have a couple wanks during the week and a couple days later try and have sex I cant cum

Any ideas on why this is I dont think im doing death grip or going too fast but I suppose you never know if you are or not

For context I struggled to cum when first having sex took a month of no masturbating and lots of sex for that to happen been better since tho

Is there something wrong with me
