Like I said, I LOVE nature. And ejaculation is a part of nature. I also feel that where you ejaculate is a part of nature as well. So unless you're doing a porn shoot, I believe you should make most of your ejaculations from anal and/or vaginal sex happen while your dick is wrapped in the warmth of either an embracing ass tunnel or a tight, wet pussy.
Now, whether or not you wear a condom with that ejaculation, being that you're an adult, I won't preach to you on that decision. That is up to you.
FOR PLAYING INFORMED IS PLAYING SEXY. ;-)
