Is it ok for me as a straight guy to put a dick in my mouth?

So I (27m) straight male for some reason want to just want to try and see what it feels like to have a dick in my mouth.

Now to be clear, I (27m) am 100% POSITIVE I (27m) am straight. I (27m) know this would be a point of contention but I (27m) can assure I (27m) am only attracted to women (5f) and pussy. I (27m) simply want to try it as a curiosity and experimental purposes. I (27m) dont even care to make the person (5m) cum, I (27m) would just like to have it my mouth for a little while.

Now the reason I (27m) ask if its ok is because I (27m) mentioned this desire to a friend (32m) in the LGBTQ community and he said it would be dishonest of me (27m) to tell a guy (10m) I (27m) was gay so I (27m) could blow him. I (27m) agreed and thought if I (27m) do go forward I (27m) would explicity say that I (27m) am a straight guy so there is no deception. My friend (32m) said many guys (10m) would like this idea and would enjoy being my guinea pig of sorts.

I (27m) just wanted some outside opinion of whether its ok for me (27m) to experiment like this or for some reason it would be unethical. Thanks for the input
