I was hanging out with my boyfriend today and he was feeling a little horny. I'm not ready for sex and he understands but I was giving him a hand job and I started using my thumb on his tip. He got turned on very quickly just by me making little circles on his tip. He even came from that. I'm not sure if any of you girls have done this to your SO but this something he'll probably love. My boyfriend said that he would have had sex with me if I didn't have my period. It turned him on so much!
