DT is based on multiple factors like gag reflex, breathing control, length, girth, head angle and angle of entry. It's also perspective in the sense it can be balls deep, 75% deep or halfway. If the length and girth is not known then is there an overall revelance to the DT in the review as some punters may look for DT (excluding DT girls known for DT) when choosing a girl but without knowing the size or girth it's impossible to know what the true reality of the DT is.
A 4 inch DT balls deep is different to an 8 inch DT balls deep and so is 6 inch balls deep vs 8 inch 50% deep.
Is there a meaningful measurement to know the reality of DT in a review without really knowing the size and if no what is the true relevance of it in a review?
