There are a lot of places in HCMC and Hanoi for extras of all sorts/ you just need to look around

Massage with extras are everywhere, and I usually scope places out in the day time as the girls have less customers and give a better service, although the better looking girls tend to work at night in most shops

Massage - if you want the full extra service Dubai massage and others listed on this forum give you some good options, but most of these girls dont do FS/ just massage/BBBJ/DATY/CIM etc

Some of the girls will connect on Zalo with you so its a good idea to download this app before you go - unlike WhatsApp it doesn't share your phone number so you can remain more anonymous.

APPS
Zalo is the Vietnamese social media app to use with local girls. there is no " nearby" functionality like wechat so its more for once you meet someone in a shop and want to take it further

Whattsapp is very popular but i don't like the fact that it shares your mobile number so unless you are getting a local SIM card it can be an issue
WeChat is popular with the working girls and home massage services - lots of fake profiles and fake pics so always video call the girl before you book to see if they are actually the one in the pic
Tinder - again mostly working girls so same as Wechat
Vietnam Cupid ( website) - there are a lot of VN girls just trying to get out of Vietnam countryside by meeting their "westerns knight in shining amour" - and some working girls on here too/ also some genuine hot chicks who want to meet westerners and practice english etc

I use some of the following:

1. Linkedin - I posted about this in this forum last year - look for hot young professional girls who want to meet interesting foreign men - they will want to talk business but after a few drinks or a second date they will usually want to fuck. The executive types are looking for a no strings attached hook up with western men. This is because most VN men don't respect women, and the younger ones that have money are either arrogant or snowflakes - so a strong, respectful foreigner who listens, takes time to notice them etc usually gets some hot sex with a non working girl who just wants to fuck.

2. Showaround.com - this is a private local guide platform where you pay a subscription ( $15 per month) to find local tour guides, many of these students want to make some money with the occasional working girl wanting respectful hook ups - I have fucked about 15 VN girls from this site

3. Massage Republic - working girls only but sometimes you find a gem

4. Home Massage Services - just google these - when you message them ask what they offer and they will send you girls who are willing to play for pay.. many are hot girls who come to the city to make a bit of money so they can go home and study or support the family. I have met many hot local girls this way and have a lot of them on Zalo who come and fuck for free now.

5. Massage shop girls - many shop girls come from the countryside and live in the shop - they make around $50 per week if they just do legit massage and live in the shop afterhours
Many of them are hot and sexy but dont realise it yet.

I usually find one of the hottest ones at a shop and go get a 90 minute legit massage with her/ get to know her and tip her well. if they are friendly I connect on Zalo then see if they want to come and hang out with me - sometimes it takes a 2nd legit massage before they are comfortable to do this, and they have a curfew ( closing time) at the shop so they can get back in before lock up - unless you want them to stay the night.

I have had some great sessions with a lot of amazing hot VN babes by meeting them this way and they are not working girls so usually they are usually more of a GFE.... and of course there is more of a challenge then a PAYG service.. I still tip them well and always buy chocolates for them as a gift

Be warned that some "legit" massage girls may have 4 or 5 clients who they see outside the shop so always cover up !!

I met one girl this way who was super hot and sexy and when I did some digging and found her Tinder account/ Insta/ TikTok - I saw that she was being sponsored to go to Japan/Hong Kong etc by various clients - so she certainly wasnt some country chick who has nothing - she ended up going to live in the US with s punter, got married, and is have a child with him - so as always - be careful especially if they want Bare Back as it may be a " get them pregnant scam"

I find the best way to find good local girls in VN is to stay away form the sec shops/ Kareoke etc and just troll the shopping centers/ coffee shops etc
