Boyfriend (24M) has phases of low libido and high libido. What can I (23F) do to help him? /u/SandycornIsAUnicorn Sex

So since we got tgt 3 years ago I noticed my boyfriend has these phases where for about approximately 6 months he’ll have a high libido and gets turned on easily, masturbates occasionally and has sex with me etc..

then after that he’ll of a sudden switch to a low libido phase where it would last about 6 months where he wouldn’t even masturbate, no sex Ofcourse and what’s even more weirder is that during this low phase he’d get disgusted when I casually just make any dirty jokes. It’s like a sudden switch of personality and anyth sexual (even talking about it) is a no go for him… I have no idea what’s going with him and how to help him with this as it’s been going on for 3 years+. It’s like 6 months he’d be high, next 6 months he’d be low… during his lows I’d have to becareful and not accidentally speak anyth that’s dirty if not he’d look at me as tho I just committed a crime.. But during his high he’s definitely not like that.
