My best memories must be giving rather than receiving. I've often found receiving to be a disappointment except the one time that I deep throated, but he still managed to spit out a drop. I often detect that the person giving doesn't really want me to come in their mouth and finishing off with the hand is normally more intense. On the other hand when giving I love that taste and swallowing it. Except once, a guy wanted to finish by hand and came all over my face (at my request). I managed to catch a drop in my mouth but wanted more. That's probably my best memory.
