Is there anyone here with a list of SHOUJO or JOSEI age Gap female older, there's a lot of male older than their lover

I don't have one myself, but there are lots around.
Here's one: http://www.mangago.zone/home/mangalist/85851/
And, if you want a different one, you can look at the recommended lists for most of the manga on that list to find more.

Is there anyone here with a list of JOSEI OR SHOUJO being an older female with a younger guy

You can search "Older Female Younger Male" as a tag on Baka Manga. Here's the josei result: https://www.mangaupdates.com/series.html?category=Older+Female+Younger+Male&genre=Josei&perpage=50
Other than that, I second Kimi wa Petto. You'll also probably like A Bride's Story, a personal favourite of mine with an age gap similar to My Boy's.
Others I can remember off the top of my head:
* Miageru to Kimi wa
* Love at 14 (Secondary couple)
* Dokuhime

Amazing manga. Highly recommended the only backlash is there’s no kissing scene ヾ(❀╹◡╹)ノ~

No kissing scene....
What is this then:

Did they end up together or not? The links to the RAWS doesn’t work now
