i’d work a routine for both if your just gettin used to pe. if you do both it will give you a good base for the more advanced excersises later on.
Use a regimen like this:
5 min hot wrap warm up with 100 kegels( every 10 do a reverse kegel)
ten 30 sec streches of your choice ( v, jai,a, whaterever)
4 sets of 50 jelqs( try alternating from overhand to underhand grip)
5 min hot wrap warm down
altough you dont have alot of time, still try a concentrate on each excerise, so you got the most out of them. if you got a comments reply back to see if i can help
