Abdullah Rahman was seen by a woman at a bus stop in London Road Brighton.
The 39-year-old Bangladeshi asylum seeker undid his trousers and exposed his genitals, a court heard.
He asked a married woman if she wanted to go back to his home after he groped her.
Then minutes later he squeezed another woman’s buttock in Trafalgar Street.
Rahman was swiftly arrested and identified by both women.
At Brighton Magistrates’ Court he admitted public nuisance by indecently exposing himself and two counts of sexual assault by touching.
He was jailed for 18 weeks over the sex attacks.
