I don't particularly like the taste of my own, pre cum tastes different and is nicer but another guys cum from inside my gf is always super sexy.
When big Pharma finally comes up with a flavor-your-cum-like-chocolate-pill, it will be the biggest thing since Viagra. They'll have to give it a good name for when it goes generic, like Cumchocoinablab or something.
When I was single I had a girlfriend who was second generation Japanese-America. She told me that Hagagenes were very hot and exciting to asian women. She was fond of a man with a well groomed chest hair. That being said, she found,and that caucasian body odor a breathe were a real turn off. She recommended reducing dairy and egg consumption, and be selective in your choice of protein. Once I had complied with this simple request she said that my breath and semen were yummy. I know the now that she is older, will et eggs incorporated into a lot of dishes. You figure it out for yourself or just ask the lady you like.
Acidic, slightly metallic. Not a bad taste, not a good taste either. precum is sweeter, even kind of taste good. Speaking of my own of course, never tasted anyone else's
Once had a brief affair. My fwb introduced her married gf to me. She was filing for divorce (affair only lasted a month or so), and while she fucked like a rabbit, she told me her husband didn't want her to suck him. Just wouldn't let her. One time we had just a few minutes, not time to get undressed, etc. and she slid down me. I could tell she was really enjoying having one to work with, and she was good at it. But when I got close to finishing I worried if she'd ever had a man's semen in her mouth and how she would react. I told her I was getting close and all I heard was a humming sound. So I came. Now try to picture a hungry calf on a teat. She held on, swallowing, until I had to tell her there wasn't any more. I got a job offer, moved away and we lost touch. Dammit.
