Small dick

Me and my boyfriend are very serious!! We love each other dearly and our connection is amazing!! We have talked about married and living our lives with each other..... butttttt he has a rather small dick (5 inches) and he can not make me orgasm and he can rarely make me cum😬😬 I really want my boyfriend/husband to pleasure me well and he is not able to do that and I’m lost on what to do... help..
