I certainly concur that the gay Dongtan beach has changed for the worse over the last few years. The encroachment of women and families, particularly Russians, and the shortage of attractive boys are both negatives.
Most days I turn up at Dongtan about 2 pm, having spent the late morning in the gym. I buy a cooling drink and do a bit of reading, but inevitably I start looking around for eye candy, but in March It seemed in short supply, although there was usually a group of boys playing handball at the edge of the sea.
I occasionaly invite a boy to accompany me to the beach, but unless there is money involved I think they like to meet up with their friends. Also they are often shy and dont like wearing brief swimwear.
Maybe Gayromeo has had an effect - there seems to be more and more boys and farangs using it, but surely lying by the warm blue sea is better than crouched in front of a screen in an internet cafe or your room.
The bars in the Jomtien Complex dont really get going until about 6.00 pm and I found the Bamboo Bar to be the same. The policy of the Samsuk Sauna is not to admit money boys, so I found a load of older guys wandering about wanting sex but not finding it.
So really I think the best option is to chill out relax and wait for the evening fun.
