He is IMPOTENT.<br />
Tell him you will love the physical closeness, even if he doesn't / can't satisfy you.
There are a million and one different reasons why couples are incompatible. <br />
Don't you deserve a better relationship than this ?<br />
Your boyfriend seems to be doing the best he can do in a relationship that will never work out.<br />

No. What you feel is normal. You should be able to talk about how you feel. If you can't have this conversation, then sexual orientation is neither here nor there. Communication is vital to the health of any relationship/friendship.
i think maybe he is confuse himself.. there a tons of questions to your answers and only you can slow talk to him and find out more and take note of how he behave like does he look at man when going out. Does he ask you question about woman? All this can tell a person feeling towards himself and others. goodluck.
