Curious... Wanting to give it a try, but not sure where to start.

So I've been wanting to 'explore' with other men, but I am at a loss of where or how to go about it. I am very happily married man and my wife and I are beginning to explore our sexuality. Part of our exploration is into being with someone of the same sex. I am actually quite excited to try it, I do find people of both sexes attractive ... but I am a little afraid of being viewed badly as someone just looking to use someone else to get my 'fix', Ideally, my best situation would be finding someone to have a fwb style relationship with. How would you recommend I approach my situation? Keep in mind i have never even kissed a man... Or even know what my 'type' is... I know very well what i like in a woman, but I am unsure what exactly is that i like about a mans body or personality. I also consider myself very 'sexual' and have a high libido And just to clarify : wife and I are in a poly/nonmonogamy style relationship and are very happy to explore together and separately. She already has a fwb with a very fun pansexual gal.
