Gf (F30) almost has no sex drive and I (M27) am frustrated

tl;dr what to do if my girlfriend has no sex drive which gets me frustrated

Hi,

my girlfriend (F30) and I (M27) have been together for 5 years now and we’re generally happy (living together, same friend group, humour, etc.). But for the past 1–2 years our sex life hasn’t been great. We barely have sex anymore — maybe once a month on average — and sometimes I feel like she only does it to make me happy, without much excitement on her side (after 5 years I can read her face pretty well).

Besides being rare, the sex itself feels kind of repetitive. I usually initiate, do foreplay on her, and then we move to the ‚act‘. She almost never does foreplay for me, even though I’ve mentioned multiple times that I’d really enjoy it. I’ve also brought up trying something new, but she never seems very interested.

When I talked to her about this, she said her behavior is normal for her age and that I’m just too sexual. And to be fair, she’s partly right: I do think about sex a lot, and right now I’m in a phase where I feel very sexual (probably partly due to the frustration). She also told me she’s just not a very sexual person — she doesn’t think about sex often and doesn’t even masturbate.

So now I’m stuck feeling unsatisfied and frustrated. I am starting to think if I want this my whole life or if i am just too much sex orientated.

Has anyone been in a similar situation? How did you deal with it or make things better?
