My boyfriend

Last night, my boyfriend told me that he's a bi. We've been dating for 7months now and he have decided to tell it to me. He have never told anyone about it except me. At first, I was surprised and shocked since I didn't know and I didn't saw any signs. With him telling to me means he trust me a lot and I do appreciate that but now things have been on my mind like what if I don't satisfy his sexual needs and would look for another person? And right now we're in a long distance relationship. He said he really wants me in his life and would like to continue with what we have. I do love him and I accept him whether he's straight or bi.
