18 and 22??

I don't think it's advisable whichever way round the genders are. Those four years are a huge time of growth. (I'm old and jaded so could be out of touch)

I personally have never been attracted to a guy younger than me, especially back in the early 20s, most guys are especially immature and idiotic 🤣 however if you are, the age difference itself wouldn't phase me, as long as it's legal and no power related manipulation at play, I don't think 4 years is anything, I was 18 when I met my now husband who was 25 at the time, some people probably think that's weird but it really was not, we've been together for 10 years now, married with a baby, I'm still more mature than him, always have been 🤣

I feel like it depends on what kind of ‘18’ year old he is. I know I was beyond my years at 18 and was mature, but if they have the typical mindset of an 18 year old and lack the maturity, then to me they still have a childish mindset. But it’s down to how you are feeling.
