Yes,

Aids can be caught through any exchange of blood, body fluids even through oral sex.

As for Herpes Simplex

Herpes Simplex 1 is usually caught via close skin contact, for
example kissing. Herpes Simplex 2 is usually caught via sexual
activities. Herpes Simplex 1 causes Oral Herpes or cold sores and
Herpes Simplex 2 causes Genital Herpes. Both types of Herpes
have been known to transfer to other parts of the body and
also to be highly contagious. Both types
also result in repetitive outbreaks but may also be latent
for years.

Herpes is mainly contagious when there is an outbreak. However
the period just before is also a substantial risk period. It is also possible
to spread Herpes even if you have never had an outbreak although this is rarer.
