Welcome to HCM
We understand your concerns
I went through your description of the problem carefully. With the help of candid
B lotion, I hope you could have a free motion to your foreskin. Without the free motion, you may not be able to clean your part under the foreskin properly and that is the main reason for the strange odor from your penis. Urine, semen, pre fluid, dust and other microorganisms combines inside and behind the foreskin and creates odor as well as infection in later stages if left uncleaned. Clean the area always and keep it hygiene.
Strange sensation while touching the penis head is very common. Penis head is not always open and the skin there is a bit sensitive to touch because it is very tender. Don't worry about the strange sensation because it is quite normal.
Hope I am able to answer your question. Available for further queries.
