What Are The Risks Of Developing STD Post A Body Massage?

Question: Hi I have an STD question. I had a massage last week. The massage was from a female sex worker. She looked in good health. She was naked. I was naked. No genital contact took place. There was no kissing. I did not finger her. There was no sex. I lay on my front on a towel on a bed. The towel appeared clean. She gave me a short light massage on my back, just gentle stroking and a bit of slight pressure back. This was followed by me turning over, her placing massage oil on her hands, a reasonable quantity as I recall and then rubbing the oil onto her hands. She then masturbated me to ejaculation. She then wiped me down with a tissue. This whole thing was quick and with the oil felt very smooth / not rough. I had no obvious skin breaks or lesions. I have none now. I don't feel like I have caught anything. Up until this point I have had a very safe sex history. I understand that this is not a risk of HIV, but I am worried about the risk of Genital Herpes being contracted here as I understand this can be transferred from skin-to-skin contact e.g. through Herpes Whitlow. I have no symptoms of Herpes but I also understand it can be symptonless which leaves me worried. I also feel guilty as I married. This may seem irrational to worry, but I am worried and am waking up at 3am each morning now and cannot stop thinking about the problem. Is there any sense you can give me of the odds of contracting a STD from this scenario? I hope they are low, it feels like they should be, but I almost feel neurotic, when I read something like theoretical risk of x,y,z that to me means I could have caught it, leaving me extremely anxious. Is there anything you can tell me to help me be able to take assurance that I am worrying unnecessarily, or, should I be looking at getting a test? If I hear from a specialist I think I might be able to stop googling and working myself into a state and hopefully get some sleep agaiin.
