A week ago, I gave my boyfriend a blowjob for the first time. The next day, he said he was tender on the head of his penis and that it was like a burning feeling (like an irritatble rubbing). Last night, he said the tenderness went away for the last couple of days. This morning, I jacked him off... about 3 hours ago. He just informed me that he's tender again. He said, at the tip of his penis, it's red and has a tingling burning sensation. When we have intercourse, it doesn't bother him. Can you explain why he would be so tender one way and not the other? He's does not have any itching or any kind of other complaints.

Try some savlon (make sure not to get any inside) to make it go away.

The tender redness is obviously irritation of some kind which he gets from your hands and mouth, try using some soft hand cream on your hands throughout the day before you tug on his salami ;) also try washing your hands before, a shower or bath is good. Cover all the angles. Change your toothpaste, might have a dodgy reaction - doubt it though, never heard of someone being allergic to toothpaste :P

Leave it for a couple of days, if it persists have your man go to a doctor for a checkup.

That's how I would approach the situation if I were in your bf's shoes, so to speak.

Hope this helps. :)
