i notice some discharge when my husband comes closer to me and intimates me, though our private parts will not get in contact with each other and we'll not have intecourse... do i need to make ghusk

The discharge could either be Mazi or Mani. Mazi breaks Wudhu only and Mani breaks Ghusl. Mazi emits when one is aroused and Mani emits when one reaches climax and orgasm.

One differentiating feature between Mazi and Mani is after the emission of Mazi, the excitement remains and one is not fulfilled. In the emission of Mani, one is fulfilled and there is no more sexual excitement.

and Allah Ta'ala Knows Best
