Once common throughout much of western North America, the grizzly bear species currently reside in five separate populations in western Canada, Alaska, Wyoming, Montana, Idaho and Washington; and there are around 30,000 bears in Alaska.
A rebound can last forever or a week. It completely depends. If you are already looking at the relationship as a rebound then it should end soon. You will not last with a person you feel is nothing more than a rebound to you.
Re: how long should sexual intercourse last for? You are certainly above average by lasting 15-20 minutes so don't be concerned about that and the fact that you can again have intercourse a short time later would make many guys envy you. As long as both of you are being satisfied-- be happy and enjoy.owever, our total lovemaking, including foreplay and afterplay, would last for an hour. Now that we are in our 60s and have sex most every day, I last 15 to 30 minutes. My wife likes intercourse to last about 15 to 20 minutes the best, using 2 or 3 positions, so it is about perfect now.
