At least 151 orcas have been taken into captivity from the wild since 1961 (including Pascuala and Morgan). 1  127 of these orcas are now dead. 2  In the wild, male orcas live to an average of 30 years (maximum 50-60 years) and 46 years for females (maximum 80-90 years). SeaWorld holds 24 orcas in its three parks in the United States and owns (at least) a further four at Loro Parque in Spain (ownership of Adan and Morgan not verified).
Many people believe that you are MORE LIKELY to conceive if you lay on your back with your hips elevated for 15-20 min after ejaculation. You CAN get pregnant if you dont do that, or else no one would use birth control, they would just stand up.
The rest wll come out when you stand up --- whether you do it a minute or an hour. If you want to wait (and can), staying in bed for 10-20 minutes should be more than ample. The best thing you can do is just lay in bed for 30 minutes and let the sperm do their job. Feel free to shower, pee, etc after that. I think it's a myth because when you think about all those people who got pregnant by mistake didn't wait to urinate or do a hand stand!!
