It's no stranger than swallowing your own saliva, really.
Ejaculate (and the sperm within it) are a natural bodily fluid just like saliva, or tears, or anything else. Yeah, it wasn't designed to be eaten (nature has other things in mind for your cum), but it certainly won't harm you. We are a curious species, and we learn from experimentation, so it's reasonable to taste your own semen, because it will give you some idea of what to expect if you encounter someone else's -- as you very well may during the many years (and various sexual encounters) of your growing sexual "career". It's also a neat, and exciting "coda" to each masturbatory session, and there's less to clean up, right? Sooner or later, most boys do reach the point of tasting their own semen, just to see. Personally, I enjoy pre-cum more, but to each his own as they say.
And BTW, eating your own cum doesn't make you gay. So, Good Luck, and enjoy!
I also love telling people online about my fetish for eating and swallowing my own cum! I even posted a bunch of videos on a porn site of me shooting my load directly into my mouth and swallowing my cum! it’s such a turn on knowing that other people are watching me swallow my cum!!
What’s stopping you? Just do like I do and flip your legs over your head and jerk off directly into your mouth; you’ll most likely, automatically swallow your cum like I do, without even thinking about it.
I've been eating my own sperm for almost 7 years now and find it to be the great finish to a masturbatory session.
