My hubby is good to go 98% of the time but there have been rare occasions where he just can't finish. I can probably count on one hand the amount of times it's happened in our 8 years together but it still sucks when it does happen and I always inevitably blame myself ?  he assures me its not me and I know some of the times have been because he drank too much and I have a feeling the rest has to do with sensations because hes only partially circumcised.  What are your experiences?
