Posting with a throwaway.

I like her a lot, and she's nuts about me and a nymphomaniac of sorts. She's my second LTR ever, whom I transferred to after some time of spinning plates, which was great.

Thing is, I'm extremely busy atm (no time to spin plates,or date, or really go out), and a gf is what I need for the next 6 months or so. But I find it hard to get motivated to fuck her. I notice that a lot of the things which would turn me on about a [new] girl, like the moans and all the reactions to stimuli during sex have frequently become background noise with her that is naturally tuned out. Every now and then I realize it and force myself to snap out of it and appreciate it, but sometimes I forget, totally lose my boner after a bit, and am not aroused.

A trick I found that works is to look at porn before she comes over without masturbating, or the morning of.

Frequently I also find that the whole ordeal takes a lot of energy. These days I can no longer get a boner unless I know that there's a solid 80% chance I'll orgasm.

We still have sex multiple times a week, its just really wound down from 2-4 times a day, which I guess is natural.

Another thing is that I'm really fine with not having that much sex - my sex drive has really decreased over the last year. I know she isn't though.

Besides the sex, its a solid ltr though - meaning that I suspect this would happen to me with any ltr sooner or later, and its not inherent in her.

I appreciate the insights. During my days of heavy TRP reading, I would expect the top answer to be something along the lines of reading the sex god method (i have) and even to abandon the ltr in favor of letting the sexless life force me into dating/plating again. idk, wondering if im missing something obvious. thanks.
