Now, I am unsure if it is a joke or not, but I will take it as it isn't a joke- if you enjoy your job, then thats fine. I couldn't do it myself, as I would find it hard to form a intimate relationship with someone else if I was working in porn, but everyone is different.
I can also see your point that someone knowing you worked in porn, vs actually seeing you in action is quite a different thing. A few images of me and my previous partner turned up online when we was together from a home video, and we have no idea how that happened. All I can guess is a 'friend' went through my phone at some point. I am a man, and I felt quite uncomfortable knowing a lot of people in my area had seen an image of me giving oral sex to my girlfriend- out of the whole video this was the part the images were of lol.
Onto the actual question, do you want something small and easy to carry, or something a bit larger with better battery life or bigger clouds? For someone new I think the Istick Pico is a really good mod. It is very small, powered by one 18650 rechargeable battery, and also charges Via USB.
This would save you having to buy an external charger, and as it is only charging a single battery it isn't really an issue not using an external charger.
I would actually recommend the kit for someone starting out, as the coils are replaceable and you won't have to build anything, and it doesn't need a tonne of power to run so the battery life will be pretty good too. It also is available for a great price
