How should a muslim urinate according to Islam?

Whether I sit or stand, it seems like urine gets on me anyway. And it seems as if I need to urinate naked and bathe after every urination, but I'm pretty sure that's not how Muslims are supposed to do it. **According to the *Shafi'i* school, how should a Muslim urinate, and especially how should one deal with urine that splashes onto oneself?** I think I'm just having excessive *waswas* concerning urine, I take so many precautions and I think it's most likely that urine isn't hitting my pants sometimes but I still am scared to wear the pants to *salah*.
