I have an issue of wadiyy emission frequently may be daily 2 times or daily once or thrice in a week etc and that time i just wipe the affected area of underwear with wet fingers for 3 or 5 times and wash the penis head .if it is ok ? After that can i perform namaz with wearing that underwear ? Or should i wash underwear?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

Wadiy (a thick white fluid which comes out after passing urine) is impure. So, if it comes out of you, you should wash your penis, taking into account that only wiping it is insufficient. Besides, you must also wash the parts of your clothes touched by Wadiy, but you are not obliged to change your clothes, nor must you wash them all; rather, you must wash that part that is touched by the impurity. In case your clothes are not touched by any impurity, then you are not required to do anything and you are allowed to observe the Prayer in these clothes since they are pure.

Allah knows the best.
