Don't eat yogurt on an empty stomach. Too much acid will kill the good bacteria. Eat something else first to neutralize some of that acid. I eat yogurt every day and haven't had any gay tendencies yet, but I'll stay on guard.
Yogurt is a big part of Indian cuisine. It is the key ingredient in Tandoor dishes. One of the most popular pan-Indian dishes is a side dish called Dahi Bada which is basically thick yogurt with a fried/baked lentil ball mixed with ground cumin & chilli powder. It is the main dish in Indian Chaat (mainly fried snacks). Another popular dish is Raita which is yogurt mixed with cucumber, carrots, ground cumin & salt. It is taken with almost al Indian food. It is similar to the Greek yogurt dish Tzatziki.
Milk is not that healthy because of high saturated fat. You can change milk to healthy yogurt at home. I ferment milk, vegetables, soy bean, rice, fruit .... at least once a week. Of course, rice/fruit wine is not healthy.
we forbade yogurt in our house. I don’t need my son wearing assless chaps in the Castro district of San Francisco.
