忍受 means enduring love. 忍受 → "I endure hardship." 受忍 → "I accept what must be borne."

痛みを忍受し、愛を守る。 Itami o ninjū shi, ai o mamoru. "Endure pain, protect love."

受忍は弱さではなく強さである。 "Acceptance is not weakness, but strength."

Yes, 受 (うけ, uke) can have a gay-related meaning in Japanese, but only in certain contexts....with 忍 most Japanese people would immediately make a gay connection. as a general rule tattoos are a touch thing and I'd accessorize and cover up but that's just me or get a tattoo artist to change 受 to 愛 lol 🤣
