Blood offerings for Dieties

As an experienced pagan who's now been devoted to a specific diety for over a year, I have a question on your view of blood offerings? I have offered blood in the past with good results when doing a spell, but currently I want to offer some blood out of reverence and devotion. I am speaking about a few drops of blood drawn with a lancet, nothing dramatic. However reading on Reddit tells me a lot of people think you are bond to a spirit forever through a blood offering. My experiences don't correlate with this, I am no longer worshipping the dieties I previously offered blood to and nothing crazy happened to me. So can you offer blood to a spirit out of respect, without it ' binding' you to them or is the binding a definite given when offering blood?
