are you okay with shounen-ai? you could try hidamari ga kikoeru!
I recommend lovely complex or some of nakahara aya's other works if you want a funny shoujo manga with a strong female lead :)
for yaoi, i would recommend:

these are all pretty well-known so maybe you've read some or all of them already...but i think they make great re-reads as well!
I am looking for a manga to read. it can either be a shoujo with a strong female lead or mature or really funny- it would be great if it had all three or a yaoi that has great character development or the relationship progress naturally.
