I have few questions/doubts: 1. My glans is having certain spots over it which I don't know are normal or something alarming. 2. My foreskin connected to glans is unevenly attached and detached. sometimes during intercourse, I feel rashes over it, even bleeding at times. 3. Slightest tapping on testicles also feels bothering and near lower abdomen. 4. Whitish residues get accumulated below foreskin between glans. 5. I assume, I reach last point too quickly. please guide me about above topics.
