Question
2 questions: 1-can you get re-infected with chlamydia by swallowing semen (we use condoms during intercourse because he hasn't been treated yet), and 2-can a female impregnate herself using semen from a used condom and a sex toy (my boyfriend's ex claims baby is his even though they always had protected sex)
Answer
Oral sex can transmit Chlamydia even if ejaculation does not occur. Other sexually transmitted diseases can also be transmitted this way including gonorrhea and syphilis. HIV is less likely transmitted through oral sex unless there are open sores. Therefore condoms are recommended even with oral sex. If your boyfriend has not been treated he needs to be.
It is unlikely that impregnation can occur using semen from a used condom and injecting it into the vaginal canal or through use of a sex toy.
