So my husband and I have been married for about 4 years. And he is uncircumcised and usually intercourse lasts quite a while. Like 15-40 minutes. Some times a little less. But the other day I was giving him a BJ..and I've never done this before but I just focused on the head the whole time. I didn't have his full penis in my mouth I just played with the head.it was only 5 minutes or so....then I got on top and like literally 15 seconds later he came.... And I quess my

Question is are uncircumcised men's heads more sensitive or something because he's never finished that quick before...?? I don't know if it was just really really good or if he just masterbated and I just finished him off....weird and TMI but...
