Full edit/redaction: 💜 Sorry for late reply. I hadn’t checked OP’s profile and incorrectly assumed they posted here to avoid ftm transphobia. Since I framed my advice specifically for ftm affirmation based on that assumption, it’s not as relevant to OP. Sorry for treating you as a cis aggressor unfairly. Appreciate you.

Attempt at useful advice:

Partner is mtf and totally agrees with you re: the lasers. She usually also discusses hair color as a consideration since hers are dark which increases the effectiveness of each session. Since I like her hair and like when she doesn’t shave, I’m a little biased, but she uses a common brand of articulated cartridge razors that surround the blades with a thick soap block. They seem to make cuts and razor burns impossible. She has only used my safety razors when she was treating keratosis on her shins.

All my best to you and OP
