i think that's a fairly normal though/impulse/whatever for people that have been in relationships for a long time. maybe i'm wrong, but i've had feelings like this when i was dating someone and i know other people that have too. i think what's most important is that you recognize it's just another intrusive thought/feeling... and nothing more. what makes you human is that you have the ability to process it and reject it as something you'd rather not do. i think you're already on the right track, since you realize acting on them would hurt your girlfriend.
in terms of a real solution, just keep rejecting them as something just intrusive. you may need to reignite a spark in your relationship to make yourself feel a little more attracted to your gf than before. try different things in the bedroom, going out to different places, etc. there are a ton of resources online and offline for ideas on how to do new things in your relationship. good luck OP.

How often family? Are you pining for new puss like every day? That's not helpful.

If it's rare then who cares. You aren't going to act on it and it doesn't matter.

You likely settled into long term too early, nbd. Stay committed and just keep dismissing the thought and it should eventually go away.

Shit... Thanks a lot. This is my first time on /adv/ and I didn't know it'd be so helpful. Guess I'm just used to the other boards. Thank you though, this was genuinely helpful.

this isn't a fork in the road mate. how long have you been together? chances are you ARENT going to be together forever and you can go get your dick wet then.

dont think of this as 'i dont want to hurt her feelings'. you cant be with someone just cuz you dont want to hurt their feelings.

the question is this
>do you love your girlfriend enough to say 'i want to keep her in my life for the forseeable future!'

if yes, then stay with her. you will likely get your dick wet after the inevitable but later break up. but if you cant say that^ then break up with her
