Nothing turns me on anymore

I once thought that my libido was going down when really I was having mindless sex with men I was barely attracted to. Now if it's my boyfriend (or before I met him, someone I had a crush on) I can really get into. Some days are also better than others. Sometimes porn gets boring so I've even had to get into weirder stuff so it's not the end of the world. Maybe explore WHO your having sex with and/or your relationship to them. That could enhance the experience. Also, give yourself a dry spell for a while so maybe you'll appreciate it the next time you masturbate or have sex

I think this isn't uncommon at all for guys who watch loads of porn, but I have no idea how common it is for women.

I wonder if it might be the same desensitisation that men experience, of if it might be due to something else, such as some degree of depression, prescription or recreational drug use, or the hormone issue Maid mentions.

Twelve is pretty damn young to be hitting the hard stuff already, and I have to wonder how and why that happened. Maybe there's stuff that you've buried way down in your head, it's starting to surface now, and so you're feeling very conflicted about sex?

Or maybe there's just a negative feedback cycle going on. If you're preoccupied with worrying about how long it takes you to reach orgasm, it's more likely you're going to take longer to reach orgasm.

Have you tried taking a total vacation from porn and masturbation?

Probably watched too much porn. Starting at 12 with hardcore porn is pretty early also.

You might have hormonal issues .

Maybe I am lucky but I am mid-40's and what it takes to get me off has increased only a little over my life time. Most of it is tame enough for even youtube.
Sure I know a lot more of what is out there but I do not need anything extreme.

Go darker. Like "Brazilian lesbian slap fetish" dark

M/21-feel the same, I sometimes worried how extreme stuff I jerk to..
But no problem with time, I can finish myself in 2 mins or in 4 hours.

I think there might be a combination of things going on. Yes porn addiction is a thing but generally it's more propelled by an active libido and yours seems to be as if your actual arousal is dropping off which maybe might be a hormonal imbalance. I'd say bring it up to your doctor and see about getting a test on your hormone levels to start with and then go from there.

No I think what will happen is that the older you get the more your testosterone drops and the less you care about sex anymore anyway. Sex is so overrated. People carry on like its needed in the same way as air. It's not.
