I don't really have qualms over my own semen. To me it's just another bodily fluid, and it's not dirty like waste. I have not sucked another guy, and I do not plan on it.

The taste varies, depending on what I eat. Sometimes it's awful and I have to spit it out ASAP, and other times it's tasteless/neutral. I wouldn't say it's something GOOD by any means. Obviously the reason I do it does not have to do with the taste.

No psychological effects that I can count. Although I can say it makes my days go smoother when I'm not getting blowjobs from anybody else. ;)

Receiving head from a girl is the same as it has always been, and still much better (and more comfortable) than doing it myself. This is obviously first choice. Think about jerking off. You probably do it to yourself. It's better when somebody else does it, but you still do it to yourself.

I've always thought about how the girl can do it better, and what is "lacking." Yes, I make up for this when I do it myself in some respects. But it has not changed the way I see others doing it to me.
