My (now ex-) girlfriend wanted to get one back in 2012 and she was so scared she had me accompany her into the room and watch while the male OBGYN installed it. Needless to say it was a very rudimentary procedure, and I was surprised no anesthesia was used.

Also, I routinely felt it with the head of my penis during intercourse, and I don’t even have an especially large member. Although they are probably the best long-term contraceptive atm, there are definitely serious drawbacks to them that haven’t previously gotten widespread coverage.
