just go and read the stories in /r/DeadBedrooms/

I have my own issues which include sex, my gf is similar and I am no expert, just a redditor.

my no expert opinion, porn is 100% ok. We have to burn the steam.

it is not cheating, it is normal, in my no expert opinion.

From what I've read in the sub I mentioned, sex drive for her is normal (for her) and it is not likely to improve, at least in the long term.

Now, the high sex drive partner will become miserable in the long run.

It can happen to men or women, and no one is at fault. It is just a very tough spot to be in for both.

I wish you all the best, but in my no expert opinion, it is not meant to last =(

same goes for my relationship, which I would love to share, but it is not my post.

Are there alternatives? Well maybe, like allowing the high drive partner to have sex outside the relationship, but this is a huge shot which 99.99% of people won't tolerate, so it might be just a no go.

It is a very tough situation. I want to be constructive, but chances to change and be happy with a solution, like having sex twice a week, will prove to much for one and to little for the other. And you are still very young. Sex will only go down over time, and it is likely to go to zero if there are kids later.

Redditors in the sub I mention are better suit to comment on this issue.

I recommend to ignore my comment, and post this on that sub and see what comes up.

I wish you all the best.
