Similar to what Bat says above, I have set myself the challenge of only allowing myself to cum when I am with a woman.
So far, I have only positive things to say. My desire has increased, my enjoyment of the whole experience is better and - for those who care about such things - my volume of cum is way more than before. I am 52 now but I am cumming as I did in my 20s - not of particular interest to me, but it was certainly a real surprise!
I realise the OP was asking about multiple pops - I've never been able to do that, so I can't say if nofap helps in that regard. But certainly, for me, it has greatly enhanced things in general.
