One PCSO, known only as 'A' for legal reasons, claims Sussex PC Steven Green watched her changing in the female locker room and had given her a shoulder massage without her permission.
On one occasion PC Green had taken a picture of the junior officer from her Instagram account and had it printed on a cup for her as a gift which read 'Brilliant but not perfect'.
PCSO A returned the gift with a note saying 'thank you for the gift but no thank you'.
PC Steven Green watched a female colleague changing in the locker room and gave her a shoulder massage without her permission, a hearing at Sussex Police headquarters was told
The incidents are said to have happened between May and July 2020 at Sussex police stations and were raised to a supervising officer.
In a hearing at Sussex Police Headquarters in Lewes, the PSCO said she had had to gestures by PC Green previously.
'I would have liked to use the mug as a gateway to tell him to back off but I wasn't given that chance,' she said.
'I feel it could have been resolved.'
Several statements from colleagues say they had seen the inappropriate behaviour and they had also felt uncomfortable.
When asked to clarify the incident in the locker room, another witness, PCSO B, said: 'The door wasn't knocked, it was forcefully opened.
'I heard PC Green say "are you decent". PCSO A jumped, it made me jump.
'I looked towards the door and saw it closing.'
PC Green is accused of breaching the standards of professional behaviour and that his actions amount to gross misconduct.
He denies most charges but admits that he pushed the door to the locker room to 'creep it open'.
In a statement made previously PC Green said: 'I was having a bit of a laugh. It was never my intention to make her feel bad.
'I didn't want to do anything malicious or make her feel uncomfortable.
'I misjudged the friendship.'
Stephanie White, Lawyer for the Appropriate Authorities said 'There was a sexual element to it and it does appear to have been directed to PCSO A.'
The hearing continues.
