Can Gay men seduce straight men?

NO. The only way a gay man can "seduce" a straight man is if the "straight" man has some underlying homosexual tendencies or curiousities. Straight and gay are not always 100% black and white issues. Most people naturally have attractions to the same sex...whether its just a casual appreciation for a specific feature of another of the same sex or a significant curiousity about being with another. So back to the basic question... no but only if you really wanted it.
