If you found me funny, that means I feel relaxed staying with you.這樣的英文語法拼字對嗎?

是有時態不合的問題：除非是＂明知與事實不合＂的假設語氣　
found 與feel的時態應該互相對應．

所以，你的原句應該要寫成：

If you find me funny, it means I feel relaxed around you. （一般假設語氣）

或是：

If you found me funny, it meant I felt relaxed around you. (過去可能發生過的語氣)
If you found me funny, it means I felt relaxed around you.

After you thought I am humorous有幽默感的( advantage) 優點, that helps we communicate well better.Feel more relax able together.

這種寫法主要問題是只有附属子句而無主要子句，所以If you find me funny, you will feel relaxed with me. 你的句子除了語法外，前後邏輯也怪怪的，就好像説“你不懂我的明白”。

If you find me funny, then it means I am feeling easy and amused, sensitive and funnily enough, emotional and sexual, about having an affair with you.

應該是If you think I'm funny, It means that I will feel relaxed with you.

拼字和句子文法獨立而言沒錯，但組合的前後邏輯則怪理/不合理/沒因果(if...then)的關係。

按原文意解是：

假設你覺得我是個有趣的人，這就表示我跟你一起時感到輕鬆自在。

「你認為我有趣」跟「我感覺與你一起輕鬆」不是因和果或前設和結論的關係。
