Female ejaculation

So When me and my SO are having sex/making love he will ask me if I'm cuming and I don't want to say No because I don't want him to feel anyway I guess,I'm not even sure what it feels like to cum really is squirting it or is there more ways to cum because I really I just don't know and I don't want to hurt his feeling saying no while having sex,but I also feel like he shouldn't be the only one to cum,are there some things I can do on my end to help me cum easier or maybe things he can do.
