When shooting only some in or trying to catch whatever I can (try the messy whip it technique if you like trying to catch it), I usually enjoy the taste and saltiness. With the tip in my mouth, it usually goes right down, not much taste. So three slightly different techniques depending on how limber I feel, and also depending on what I want to do with the cum. With the tip in my mouth, I happily suck all the sperm out of my dick. The Crawl the Wall technique will help and slowly but surely you might be able to get the tip in. If I want to really slurp cum, I get my tip in my mouth. Especially if I have a beard or any facial hair. I avoid the mirror as there is something about seeing my own face with cum on it that turns me off. If I get it all in my mouth (which usually happens when I am inverted and my dick is inches from my mouth) I often end up spitting it out, sometimes immediately. If some ends up in my mouth I try and swallow it right away, before it turns me off, like the first spurts usually. I'll aim for the face and often have my mouth open but eyes closed. I don't always get totally inverted, as it hurts my neck, but can often achieve a 'firing position' that will still hit my intended target: my face. I often start laying on my back on the bed and slide off. The Stop & Go or edging technique really add to the enhancement of this technique because they can really add to the amount of ejaculate produced, and in most cases, the more the merrier.
