User Lawlumad made a good Vietnam guide for beginner. Also I suggest using online website to find girl for example gaito. I highly recommend installing the app "Grab" and "google translate" if you don't speak the local language. I been to Vietnam like 5 times already. Got my money stolen by a russian local, got my new phone I just bough grab out of my hand from a guy driving a motorcycle at night. All that happen on my first trip to Vietnam and I went back 4 more time afterward because Vietnam is the best country I went to so far to play around. If you got any other questions about Vietnam just ask me. I also have good restaurant recommendation.
BTW how long are you planning to stay there for?
Is the goal of the trip to just stay in HCMC and play around or you here to travel and experience the culture?
Do you speak the language?
Do you have a friend who can just show you around?
