You can have six skydives a day and still want more. Finding partners for skydiving is much easier - physical attraction is not as important.
Skydiving is much safer, no diseases and no kids.
Finding good partners is much easier - everyone knows in advance how good a skydiver you are. Everyone involved is usually satisfied or not with a skydive. You can ask skydivers if they've put on weight without offending them. Solo skydiving is not embarrassing. Everyone is ugly in freefall.
