First Blowjob

So, I’ve been seeing this guy for some time now, and we have been doing a lot of the dirty things, maybe all of them but the blowjob. I’ve never done it before so I’m super scared to go down there and don’t know what to do, specially when he cum, or not satisfy him. He doesn’t know I’ve never done it and I’ve been postponing it all I can (like i did with every other guy) but I’m starting to feel guilty cuz he satisfy me in every way and I feel like I’m not doing the same :/ It would be really helpful if u could share your first experience or maybe some tips to help me feel more safe about it. I really wanna do it, I’m just terrified about doing it 🤦🏻‍♀️
