Why is she kind of stand offish the last few days?

I had my first lesbian experience a cpl weeks ago. For the longest time this woman and I flirted and 'teased' each other. Finally we kissed and touched a little..then we got at hotel room and fingered each other but were scared to go any further (oral or whatever). We also had a couple '3 soms'..with guys..sort of . No SEX just messing around with them. Then last week I hung out with her and her mom all day and we ended the day cuddling in bed and talking ...she stroked my hair and arms and back and we watched GIA ( a lesbian movie lol). But the last few days she has not been inviting me over or texting or calling as much. I asked her yesterday if she was mad at me and she said "no..never". So hope she's just busy.I don't wanna be clingy but I want to know if she's for real or not too you know?
