Any other guys experiencing a lot of sexual harassment from other men?

Just this past week there have been four blatant instances of gay men sexually harassing me.

• Two guys under a bridge in the Chiang Mai mountains. One of them just followed me wherever I went along the river and just sat opposite me and stared, it was very strange. Then as i tried going up to my motorbike, they kind of stood in the way and his friend tried grabbing my crotch

• A Korean tourist flirted with me (non-reciprocated) with sexual undertones in a hostel bathroom.

• Today, a HongKong-tourist followed me into a public bathroom in Bangkok, he used the urinal behind me (didn’t even pee) and then asked something about changing my shirt. He seemed like he wanted to follow me into the toilet stall (but I didn’t let him) and then he followed me over to the handicap toilet (separate door outside) awkwardly smalltalked and then asked ‘if i like it’ insinuating penis.

• just half an hour ago, some guy walked way too close and seemingly ‘accidentally’ touched my penis with the inside of his hand.

• the cook/cleaner at my hostel (a flamboyant 60-ish year old man) asked if I had a girlfriend

(Over a week ago)
– a new muay thai trainer I had never met before touched me around my thighs and said something (presumably dirty) in Thai in front of another thai-trainer. I didn’t find it funny and asked the other trainer what was wrong with him.

These have all happened this week along with the occasional ladyboy etc. it’s starting to bother me and I am wondering if any other tourists(or locals) experience the same and if you have any advice on how to avoid it?

I don’t look gay or particularly feminine, but I look younger(I probably look 17-18) which could be a factor.

This isn’t only a question for other men, I am also curious if any women have the same problem, and if so, how bad it is.

Edit
I added an encounter I had forgotten when I wrote the post
