Is it normal to have dreams where i'm acting frigid?

in the past few weeks i've had 2 dreams about being frigid. i have recently come to terms that im bisexual, and these dreams are involved with girls (im a girl).

the first dream, i was in my room with my best friend and we suddenly started kissing and touching each other through our clothes, she started to kiss my chest, stomach, hips as she was kneeling down to take my pants off and go down on me but i stopped her and said that we shouldn't. we were both so into it and hot for each other i can't work out why i stopped it. i went to the bathroom in my dream and remember thinking to myself i wasn't wearing the right underwear so i didn't want go any further with her.

the second dream was with a completely random girl who looked strangely like the felicity shagwell out of austin powers- the spy who shagged me and was respectively much older than me (im 18), she was wearing shiny french green hot pants and crop top with long sleeves. this time, i was in the bathroom (again) and she was on the other side of the door coaxing me. i was looking at her under the door and she was talking, i cant really remember what she way saying and what we were doing but i wouldn't come out. it was all fun and games though and we were giggling with each other. after a while she stopped and was laying on her back by the door with her legs bent, i looked under the door and i had a clear view of her crotch and i somehow reached out and touched her. the whole scene jumped to us being together and it going a bit like this,
-both laughing seductively-
her- "hahaha, but no really we should have sex"
me- "nooo haha"
her- "but your sexy, we should should do it!"

then i woke up. i wake up from these dreams so frustrated and confused, wanting to have experienced everything but it hasn't yet!

for the record, i haven't actually had sex with a girl of yet but am dying to and the first dream was sort of like a scene out of a movie i watched recently.

does anyone have any reasons as to why i might be like this in my dreams? or even solutions to help me complete them
