This gay girl makes me really uncomfortable?

for starters i have nothing against people who are gay, i live in a very liberal place and believe same gender couples should have the same rights as male/female couples. but theres this girl that i know who is gay. im a girl as well. she talks to me all the time and theres certain stuff she says that really just makes me feel weird and uncomfortable. like she tells me how guys want to have s and like she asked me to go to a gay club with her. she knows im straight. and i feel bad saying it but it really creeps me out. i try to avoid her but she texts and ims me so much that i feel bad so i eventually give in and respond because i dont wanna be mean. like she talks to me ALL the time. i also have another friend who the girl used to talk to and i guess the girl would tell her about like when shes had with other girls. like its too much. what can i do about this? i dont wanna be mean because i think she has good intentions but like it really bothers me.
