Open Question: Why can't my boyfriend have sex with me?

[feedcrawler]

We have been together just over a year and when we first started dating we tried once and he got hard but lost it before we started. Then a few weeks later we tried again and the same thing happen. After that we decided to wait till he is off his acutane for chest and Back acne. A few minths ago we fooling around but thats all. He has a huge foot fetish so I'll tease him by laying with my feet towards him and he'll start messaging them and hell get really hard and well fool around and he even stays hard when I go down on him until he finishes, so theres no problem with us fooling around. Last night we finally decided to try sex again and he couldn't get hard at all, even rubbing my feet did nothing and it ALWAYS works. Why can't he stay/get hard for sex. Wvwrytime this happens I feel worthless and unattractive and breakdown and cry even though he swears it isn't my fault at all. What can I do to fix this problem??
