Blowjobs

Soo... Its gonna be our one year anniversary with my boyfriend. We were both both virgins, and I’ve never given a blowjob and I want to amaze him... He has been asking for a while but I have no idea how to so I kept postponing... How do you do it? I know this sounds childish but a i really want to amaze him since he helped me so much with depression and everything.. this sounds lame but please give me some tips!❤️❤️
