SEX - how do I do it again?!

Does anyone else feel like they have no idea how to even play with a penis after having a child? I think this is the longest I’ve ever gone without sex.. a WHOLE year! I have a very little sex drive, but when I do fancy it I need it there and then. Same with my partner, my question is. We do the same position every time. He’s the 3rd person I’ve slept with, we aren’t adventurous or anything but I wanna try some stuff.. can anyone throw some advise? I don’t even think I’ve ever given him a blowjob! 🙈
