Obvious stuff will show up, a tender testicle, genital warts, leucocytes on urinalysis, but the medical isn't specifically designed for std's.
Very different climate out there nowadays, sexual "disease" is blended with sexual "health."
Most of my more athletic patients seem to attend for "routine checks" yearly, as par for the course, and non report any "victim blaming" or tut tutting judgements.
Interestingly, in the UK, the Sexual Health Clinics are so so so confidential.
