Is this normal?!?!???

Hiiii...sooo I'm new to this while sex thing..i just lost my virginity to the loml like a month ago..but anyways is it strange or weird that I cannot cum. No matter the position. Or whatever. I just can't. And idk why :/ but when we do have sex he's always like "did u cum??" And im just like nah ): and I feel like he thinks that it's not enjoyable for me because I dont cum...idk. is that normal??
