self - pleasuring /ejaculation/my genitals feels different/worse suddenly

my masturbation/ejaculation/penis feels different/worse suddenly?? I've been masturbating once day for a while now and the sensation I got the last 3 days have been suddenly completely different and I'm worried, like obviously I know how my penis feels and I am used to the sensations so I had a certain masturbation technique and everything and its not like things gradually got weaker/different it literally happened in 24 hours, one day its normal and the next day the sensation was completely different and worse and it has been like that since. basically my normal masturbations my penis felt stronger and better stamina and able to withstand more tension, id be able to bring it up to almost climax point and then slow down and keep doing that, but now my penis feels a little bit weaker and I can only reach climax point once, also the orgasm doesnt feel as strong or good.. i went 48 hours without masturbating to see if i just needed to rest and its still exactly the same.... im worried its gonna be like this the rest of my life because its not like i felt it gradualy happening i just tryed masturbating one day like usual and it was 100% different, and after resting i didnt feel like it was stronger either, im planning to just take a few weeks without masturbating and see what happens...... anybody had anything like this happen to them before? help???
