Splashing of urine on inner thighs

sir/madam,i am a women i have waswas thoughts that while passing urine the urine from my private parts splashes on my inner thigh and legs so each time i pass urine i take ghusal this makes it too hard.while going outside i cant pass urine because of this because i will wear salwar while going outside so if i pass urine i have a doubt that whether the urine splashes on my pant so i cant go outside.this makes too much trouble and i cant live happily.if i dont wash i have doubt that whether the urine in my pant transfers to the places where i sit,walk and make everything impure.so please help me to recover from this and tell me whether all things are impure.
