Regardless of culture, humans have more in common than they have differences. However, there are cultural differences, and some can mean some serious issues. Many differences are subcultural rather than cultural, i.e., not all Thais are the same. My own experience plus that of my farang friends and associates is most remarkable, and I’ll do my best to structure it here.

Overall, the vast majority of farangs have Thai girlfriends from the farang bar-girl and freelancer scene. A smaller percentage are Thai ladies from the offices of multinational companies (usually met in the office), and Thai ladies attending universities (often met via Internet). A still smaller percentage is Thai ladies from none of the above, and what I’ll generally categorize as from social encounters — the general blue collar workforce, or born wealthy and idling, or supported by their extended family, etc. (Low level sales ladies in department stores and the like are often in a grey area, in-between.)

There are major differences between “mainstream” ladies and bargirls/freelancers. While there are many sorts, most of them will not get in bed with you quickly. (How long varies from a few dates to a few months. Those waiting until marriage now make up a small minority.) They will expect you to be faithful to them. You must know how to be reasonably polite and proper in Thai culture if you ever expect to get far. Sukhumvit and Pattaya norms are not acceptable — this is a different subculture.

When in public in Thailand, it’s important to not overdo physical contact. Watch Thai couples. They may touch hands or arms occasionally, but they don’t walk down the road arm in arm, and don’t even hold hands much. Nonetheless, the looks in your eyes, smiles, and gentle affectionate touching which flows naturally is quite acceptable in contemporary Bangkok culture. Of course, unnatural, “forced” contact is a turn-off. Kissing in public is something you should never do in Thailand
