Writing a song I want to know if this lyric made sense, "can't say no to my temptations and sensations probably because she's a flirtation"

In my opinion, it does make sense. If you want the message a little clearer try not to rhyme three words so close together. I recommend one of these examples if they fit the rhythm you're trying to go for.

"Can't say no to my temptations
Because she's a flirtation"

"Can't say no to these sensations
Because she's a flirtation"

Good luck song writing!
