how to massage cock

I am really struggling with a situation that’s quite personal and I feel a bit embarrassed to ask, but I’ll just dive in here. For a while now, my partner has been saying they've been feeling kinda tense and maybe even a bit unsatisfied. I’ve been wondering how to massage cock to help them relax and enjoy it more. I’ve never done this before, and I’m a little unsure about the best technique. Should I use my hands or is there a different method that’s more effective? I heard some stuff online about the pressure points that can really make a difference. Like, when I've seen videos and such, it just looks so easy but in reality, I’m worried I might mess it up. Also, do you think that the environment matters? Should I set the mood, like dim the lights or play some music? I really want to make it a good experience, ya know? How to massage cock properly without feeling awkward myself while trying to focus on their pleasure? Any tips on timing or anything else would really be appreciated. I just don’t want to end up making it a weird situation!
