I'm glad someone brought this up. When I first came out, I was inexperienced and thought that gay guys would really like that quality in me. Turns out I was wrong. When you meet a guy for a hookup - and I don't do them often - they expect you to have been around the block a few times. If you go to manhunt or any hookup site and read some of the sexual interests listed in some profiles, you'll see that they usually have a laundry lists of what they expect you to know how to do. If you have a big dick, you better know how to use it or don't bother calling them again. If you're a bottom, you better not whine that it's too big. If the guy likes feet or any other fetish, you better come prepared for that and know how to satisfy them no matter how long you've been out.
In some teen movies from the '80s, if a nerdy guy or loser ended up with a beautiful girl - but didn't really know what to do with her - she would be more than happy to teach him. She might think his inexperience was cute, giggle a little bit, then proceed to give him what he wanted. And later, fall in love with him. Some movies that come to mind are Revenge of the Nerds. With most gay guys, you can't expect the dude to just giggle and then show you how to do something sexually and actually fall in love with you or even CALL you back for another round. Gay men expect you to know how to do it all especially if you're hung. And you MUST know how to give good head. Otherwise, you won't hear from them again. I once had a friend with benefits and thought this would be a great, and hopefully safe, way to get some practice. After about five times, he didn't want to hang out with me again. Practice makes perfect.
