Building rapport with her family has nothing to do with creating sexual attraction. Don't confuse being culturally accepted with being sexually desired.
Maybe accept that you don't understand how attraction works before giving advice on how to build it. You might learn a thing or two.
Listen I admit I'm no Casanova, but I do get plenty of dates while in South East Asia and I know thing or two about being a gentleman. One when it comes to attraction, it boils down to not needing her approval, just a laid back calm presence, natural and having good social skills and figuring out the logistics of the date, If you got those things covered, you should be good to go, though I admit, my main weakness that I don't land a second date sometimes is because I'm not 'sexual' enough and don't kino her often as I should, because I'm rather conservative in that department and made a few platonic girlfriends in the long run, it's still a learning process for me and I've already had a few marriage talks with some of the long term prospects that I'm dating in South East Asia long term wise, like I said I'm just spinning my plates, the Christian way, while I'm out there and while I'm here in the states, might as well flirt with a few latinas at a few pubs, coffee shops, bookstores and all the venues I used to go to while I was here.
