Welcome to Basenotes! Nice to see another guy rocking Poison.
I wear many different female fragrances, even extremely floral or recognizable fragrances ( Fracas and No. 5, for example ), and have never had trouble or criticism from it. My favorite genres are florals and orientals, and many of the best ones are marketed to women.
Don't tell the straight guys they can't wear the sweet stuff, though, many of them are already fighting the gay cliche just for having this hobby, and how better to console yourself for ones heterosexuality being in question than a liberal application of Carnal Flower?
