I'm in my 30's now and I've had enough massages over the years that I don't get too excited by it nowadays.
The most a masseuse will notice with me, when I'm lying face down and then turn over to lay face up, is a small bump, almost like there was a golf ball resting on my groin. Nothing like the tent I used to pitch ten years ago.
So anyway right now I'm in the Canary Islands on holidays. I went for a 90-min Thai massage earlier today. I had already sent WhatsApp messages to the masseuse to make my booking, and I mentioned that I can speak the Lao language (the Northern dialect of Thai), and so she started sending audio msgs to me in Lao, and I sent some back. All clean and polite.
So I arrive at the parlour and I'm greeted by a gorgeous little 5'2" angel smiling at me speaking Lao, and so we had a rapport right away speaking a far away language in a prime European holiday destination. She looked happy and healthy.
So I'm in the massage room and I'm lying naked face down on the table, and she walks in and places a towel over my ass. In usual Thai style she climbs up on the table and is using her knees and elbows to massage me. This was pleasant but didn't result in a total loss of cabin pressure in my pelvic region.
So then it came the time to turn over, and I was only about 10% de-flacidified so I was able to easily hide it by pinching my member between my thighs. Not even the slightest bump, I was the ideal massage client.
Next came the tsunami I wasn't expecting. I'm lying face up on the table with a towel over my groin. She massages my left foot and places it about 2' to the left. Then she massages my right foot and places it 2' to the right.
So now my legs are apart and I'm lying face up. She proceeds to climb up on the table, one hand on each of my shins, and she crawls up between my legs, and moves her hands inch by inch up my shins, my knees, my thighs.
That was it. Complete and utter total loss of flacidity. I wasn't even at 90% or 95% -- I'm talking maximal engorgement. Having her crawl her way up me like that was the end to my flacid protest. The tent I was pitching was so outrageous that it would have been ridculous to even try re-arrange it. I pushed it to the side twice when she was massaging my inner thigh on each side, but I tried to do so quickly and without too much fuss.
I regularly have massages at home in N. Ireland, but even at Thai places in the UK they don't crawl up the front of your body like that.
There wasn't any genital contact but I still left with a similar feeling to having recently had sex -- although I haven't had sex in five years so maybe I'm callibrated differently now.
I asked if she wanted to go for dinner and she seemed enthusiastic. I'm here for another month so we'll see what happens.
