Bf is a virgin

Im 22 with a 3 yo daughter my partner of 11 months is 23 and iv recently found out hes still a virgin, iv only slept with 7 ppl myself 6 of them I was in a relationship with and 1 was my best male friend, my bf knows everything about me as im very bubbly, we both love eachother to bits no doubt about that and hes great with my littlen :) we have arranged to spend nye together at mine where we are planning to have sex, I can sense hes incredibly nervous as whenever I have gone down his pants he flinches and he is also very self conscious although I think hes perfect and I love him no matter what! Obvs my other relationships have failed but I do generally love him and im in love with him so its all new to me as iv never felt this way about anyone! (domestic relationship with babys dad and he doesnt see her fled halfway across country!) im just looking for ways to make it enjoyable for him aswel as me! Im a size 16 and am 5ft 8in so im not small or majorly fat but I don't like myself really as had a emergency c section and iv been uncomfy with my tummy since! And my bf isnt very big downstairs so that side of things isnt an issue for him hurting me etc! Just really need some advice I wana make his first time special and our first time as a couple special too! Xx
