Need help feeling sexy again‼️ tips tricks and advice please❤️

Okay so I’m about to be 19 weeks pregnant and I’m just curious what i can do to feel and look sexy for my boyfriend again?!?!! Things in the bed room are just getting to repetitive and starting to get alittle boring And i feel like it’s my fault but i wanna figure out ways to feel sexy with myself again and look sexy and act it for him! He works so hard and is tired a lot but he deserves someone who can make him feel like a man and i feel like i don’t do that for him anymore! When i do my hair and makeup it doesn’t do much so I’m just trying to fee sexy all over again! If any of you lovely ladies have any advice I’d love to hear it!!
