Is it even possible to resist?

I'm a straight 30y old male that's in a good relationship, but somehow as soon as my GF goes to bed I end up secretly jerking off to cocks and gay porn.

Since we live together it's almost impossible to meet up with guys and experience this for real, but I do think a lot about tasting and sucking another men's hard cock. Tonight she's out with her friends and I immediately thought about the idea of finding a random guy online to meet up and give him a blowjob.

I feel so anxious about meeting a random dude just to suck him off, but on the other hand I think about it so often I feel like this is inevitable to happen sooner or later.

Is it even possible to resist this urge for cock on the long term?
