sex question HELP ME

So is it true that if you dont have sex for a long time it affects your libido in a very negative way? I dont feel that tingle in my body. I don't get wet or anything which is weird. It wasn't always like this when i first starting having sex i was 22 now im 27. I have been in relationships and I don't even crave it or anything. I recently tried and i could not cum to save my life so i basically faked the whole thing. I need advice please help. i feel like a old dried up woman. Or could it be that I've had so much garbage sex that im just actually 100% turned off by it.
