Control horniness

Hello,

I've been on a nofap journey for some time now, but recently I've been on a 4 months streak as I decided to take the opportunity for this new year to completely cut off pmo in order to be in a better mental state - and waste less time -, for my preparation of buisness schools contests i'm passing from next may until july. However i've been much more horny as days went on and have been really tempted to approach girls, whether at my college or at the library i'm studying in (i've done a fair amount of cold approach in the past so it is pretty tempting for me). But at the same time having a girl in my life right now would be counter productive and too time and thought-consuming, i'm trying to go to the gym twice a week to keep my testoterone levels in check but sometimes thoughts of trying to approach girls are pretty distracting.
I've recently been thinking about resuming masturbation with no porn in an acceptable frequency (like once every two weeks or so) to prevent that from happening, but really don't want to. I'm here to ask for experienced people about controlling urges to get some tips on how to keep my sexual desires in check for a certain point of time. Thanks in advance
