One of the most often asked questions gay people, especially men, may have with regard to love spells is if it is possible to turn a straight man gay. Usually the scenario goes that a gay guy is either madly in love with or desperately wants to sleep with a guy they know is heterosexual. So they question if it is possible to use magic to turn a straight man gay. In a nutshell, the answer is "no". People are what they are. You can't use magic to turn a straight man gay but a gay guy can use magic to seduce a "straight man". Keep in mind that this seduction will not be permanent, will not result in love or a relationship, and will usually only manifest in a one night stand or single sexual encounter.
Let's break down the choices for sexuality. We have heterosexuality, homosexuality, bisexuality, asexuality, and a little something called "bi-curious". In order for a gay man to use magic to seduce a straight man that straight man would need to already be bi-curious. Of course bi-curious refers to people who identify with being heterosexual but who would like to experiment with a person of the same sex if they could meet the right person under the right circumstances, and probably with the help of a little friend called liquor. That's where the magic comes in, to help create the right timing and circumstances.
So there you have it. Can you use magic to turn a straight man gay? No you cannot. Can a gay guy, or lesbian, use magic to seduce a straight person? Yes, if that person is bi-curious. Will this result in love or a long-term relationship? No, no it will not.
Interestingly, there are a few heterosexual people, usually women, who want to seduce a gay man. This can be done as well. The same rules apply.
