yes exactly Rainne, Tamara we weren't planning on doing condom with TBM, I was just intrigued by why people choose to do the condom method and it appears one of the advantages is that only a very small portion of the semen / sperm get through the holes. Therefor, if this sways for girls, wouldn't the same rule apply for TBM and we only use a portion of the sperm / semen to put back rather than the full sample?
