Nothing

I agree with Allison on this one that there is clearly a confusion here. His honesty will really help out this relationship to bloom. Obviously, there is some chemistry that is working in both favors but there may be an underlying issue that he may have to address. Of course, that subject will be both confusing and embarrassing for him so be sure to use caution. Please keep us posted so we may be able to assist you.

I'm confused as you are, and the answer really depends on what his honest truth is:
- Is he not sexually attracted to you because of your weight (something viagra would not help with)
- Is he unable to have a sexual physical response to you, because of his physiology (something viagra may be able to help with)

Are you two able to be physically intimate in all other ways, and find mutual pleasure from this, but when it comes time for intercourse, he is unable to achieve or maintain an erection?
