I didnt tell the guy i was cheating with that i was on my period

Is it normal? I've been with my boyfriend for 2 and a half years. I love him to death, i really do. He does so much for me. But tell me why for the past couple of months, his best friend and i have been meeting up secretly early in the mornings. Today after my boyfriend leaves, dude calls says "can i come over?" i am hesitant because im on my period. so i put my patch on thinking that'll stop my period. he comes over and for some reason everytime i see him i cant help but get butterflies and wanna jump his bones which is kinda what we did. so i go downtown and i drive him crazzy and he pushes me off after a couple of minutes with this hungry look on his face. then, he puts me on my back and i know whats coming. he wants to lick me. oh god, im on my period i was thinking but in a way i dont really care about him so i dont care if he licks me on my period. however i wouldnt let my boyfriend do it because thats just gross and i LOVE him so i wouldnt want him to go through that. so dude licks me and it feels SO good! so then he puts it in me and starts doing me and after a good like ten minutes, he was like are you on your period? .... i said ... NO, i dont think so. then he kinda starts pounding me a lil harder kinda like he was mad, so then i flipped him around and got on top and instantly made him come making me com at the same time. it was pretty amazing, then we cuddled for a lil bit, he tells me how sexxy i am and blahhh blah blahh, and then i tell him he should go, and he goes, "oh and the redness was kinda disgusting." and now i kinda feel bad ... is this normal?
