this is tricky. It depends on the circumstances I think. If you are chasing straight guys for a relationship then I feel you will be heartbroken and doomed. However if you are just looking for sex then there's an opening. It's dangerous. Some straight guys will react violently. However sometimes it works out. I was out partying on friday night with a group a friends. A kiwi guy was there with us, straight blond about five five a litttle cute guy quiet but friendly. I flirted but he made it clear he's straight. Cool. So the night keeps going with bar hopping noraebang soju shots and five of us end up back at my apartment for more drinks.
at this point we're all sloshed and kiwi ends up in my bed with me and he mumbles something about keeping his clothes on to sleep. whatever cause im smashed too. in the morning however i find him nude (he must have stripped in the night) and wrapped up in my arms as little spoon (im six three) well my body does what bodies do and he's responding so yeah straight... but I guess open if its right? after he reiterated that he's straight. Cool. I have no reason to doubt because orientation is about who you are attracted to not who you have sex with. Gay guys have been having sex with women for centuries.
That night he ended up partying again (without me) and sunday morning I get a call from him... he's at the mcdonalds in itaewon at like six am or somthing so i jump in a taxi carry him out of mcdonalds (hes five five) and back to my place where the little kiwi straight guy pounded me again. So i would do it all over again but have no illusions about what it was.
