Question: about two weeks ago my boyfriend said the head of his penis felt raw which he thought was from masturbating. he was putting vaseline oil on it which i told him not to and to use neosporin. it scabed up to about a quater size scab. we had sex a couple days after the scab appeared. about 4-5 days later i started showing symptoms of a yeast infection. ( burning sensation, red swollen itchy, symptoms i have had once before and went to the doctors and they told me it was infact an outer yest infection) no scabs blisters or anything like that. after the scab healed he pulled the scab off and for a couple days said his penis was dry and itchy. he has been putting lotion on his penis and now has one clear watery skin colored blistered right where the scab was and nothing else. he said there his no pain but it does itch. we have been together for 4 years and neither of us have ever had symptoms of a std. should he be treating himself for a yeast infection.

the blister looks full with clear liquid in it I read online that XXXXXXX cider vinegar baths help along with the miconazole cream I'm wondering though should he pop the blister to release the fluid or let it do it on his own
