OK, people, you can laugh at me all you want but recently I found out that I'm no good with this stuff.

I'm not sure what I need to do but I know I need to improve. I really want to give my partner all I can but I lack skills and knowledge. My lips get tired, gag reflex kicks in pretty soon…

I expected to find tons of info on the Internet but seems like I failed, it's all way too general or uncircumcised-specific.

I'd really appreciate it if anyone helped me with this stuff.
