I don’t know what to do??!

My husband keeps trying to fu**k me in the as** and honestly I don’t like anal. I tried it before but din’t like it at all. Every time I’m laying down he comes and lays down as well but then proceeds to go down to suck my as** which I enjoy 😊 but after he’s finishes he starts to insert his penis which is quite painful 😖 and don’t really enjoy it at all. I don’t know how to get it through to him that I don’t like anal but he just keeps pressuring me into do it. What really gets to me is that when I say no to anal he goes and says that he’ll fu**k another women in the a**s! I don’t know how to go about this whole situation anymore.
