birthday sex

okay so my boyfriends birthday in in 8 days. im currently pregnant and don't feel all that sexy although i am finally getting my sex drive back . anyways i can't buy him a gift so sex it is lol . he's been wanting to do anal like everyday he tries sticking his fingers in my butt so i told him we could on his birthday. we've done it before and i dont like it but i dont hate it. i think it feels nice after a while but im so grossed out about the possible poop although he says its okay if it happens like he doesn't get bother by it. i can tell he wants to because the Bluetooth started playing porn instead of the music and the title was ebony anal... i don't know im just nervous. like i want to fuck but the second he goes for my butt i might get nervous. the first time we did it i was the same way and he's actually really gentle at first and like talked me through it then the next day and so on it got rougher which im totally into in general especially when theres a belt involved lol. anyways i don't know
