@mashie Americans already eat too much protein. And besides, semen also contains cholesterol so it's not all win-win, no matter how much men try to shove that down our throats. 😃
@marcot If, and only IF, your girlfriend wants to try to swallow, suggest that she do so with her mouth closed so the semen is not exposed to air and that she gulps it straight down her throat without tasting it with each spurt. Without having it sit on her tongue, she can't get a feel of the texture or the taste of it and it may be easier to swallow.
I've been swallowing ever since I first began engaging in oral sex decades ago and I still don't relish the texture or taste. For people who haven't tasted it, I can only describe it as tasting like salted bleach and having an slimy egg-white texture.
It's not the most delicious stuff on the planet but I do gain a certain amount of enjoyment from causing my lover to orgasm by using my mouth. Sometimes it's a sub thing and I know I'm pleasing him and sometimes it's more of a Dom thing and I feel all-powerful in controlling when, how and where he cums and turning his knees to jelly.
Again, I can't reiterate it enough, men, drink lots of water and eat fruit, especially pineapple to make your semen sweeter and your lover more likely to swallow it.
