Trouble sucking dick

Hi Sam, I've recently been embracing my role as a faggot in London by offering foot massages to superior men. This has led to some amazing meets where I've started by rubbing their feet and it turned into full foot worship when they realised they enjoyed me sucking their toes and licking their feet with some men even rubbing them all over my face and making me repeat that I'm their foot fag which felt amazing!

The trouble for me is that men often also want their dick sucked while they're relaxing and being worshipped but I'm still a virgin and inexperienced in sucking dick. The taste of the tip puts me off especially when they start to leak precum and I don't know what to do when it's in my mouth unless they guide me and take full control of my head. I feel so embarrassed since these men deserve full service in any way they please and my lack of experience makes me feel like a really useless fag for not being able to please them in this way.
