Is it normal for a straight guy

Its completely gay!

Just remember this any thing is Normal becuz your your own person I'm straight and I like penises only mine tho

Let's try to be sensitive here please. Many people have trouble with their sexuality. In a world where a male giving another male a compliment is considered homosexual. In a universe where a male is obligated to act a certain way or else considered homosexual, no it is not normal. Americans, along with other nationalities, consider being homosexual morally wrong. The fact that a male would consider himself heterosexual when he finds pleasure in being nude in the presence of a homosexual male would mean that there is a strong possibility that former is bicurious.
Being realistic here, most people frown upon any form of homosexuality. Although, it is morally wrong to judge someone based upon their sexual preference. If you find yourself seeking pleasure in being nude in front of a homosexual male then you should find out if, maybe, just maybe, you find having a sexual or romantic relationship pleasure as well.

Personally: Perfectly normal

Good luck!
