Risks of STD? Bump on shaft?

[marty522]

I'm a 30+yo male.  In recent months I have had several massages with a happy ending.  On one encounter months ago I had received protected oral.  Although in all other cases it was a handjob.  In early February I visited the MD for a check-up and had him look at what appeared to be a pimple on my scrotum.  I figured it might be a sebaceous cyst, nonetheless I wanted peace of mind.  He reported that it was nothing..."superficial" he said.  Just this morning, I found a small hard bump on my penile shaft in an area where I have some hair.  It is approx 1.5mm, perfectly circular, and flesh colored.  I normally wouldn't have noticed it except for the unique "massage" I received 1 day ago.  The woman got on to the table and straddled me (nude) to finish the manual stimulation.  My penis didn't go near or in her vagina, however there may have been contact between her genital area and my scrotum while she sat on me.  I have no other symptoms to speak of other than my anxiety.

So, should I be concerned about this incidental contact?
If so, what testing is recommended?
What are your thoughts about the bump on my shaft?

Thanks

Welcome to our Forum.  It is not clear to me whether you are asking two questions (about the "bump" and about the potential consequences of your partner straddling you) or one.  I'll address what I understand to be the problem but you may need to clarify things.

The "bump".  The lesion you describe is not something to worry about and almost certainly is not something that is a consequence of receipt of masturbation.  The location you describe, in a part of the body where the is hair and the description suggest that is may be a sebaceous cyst, folliculitis or some other benign process.  STDs which cause "bumps" are primarily genital warts or molluscum contagiousum and this really does not sound like either.

Part of what you write sounds as though you noted the "bump" the day after your partner straddled you during masturbation.  If that is the case, that is further evidence that this is not an STD.  There are no STDs which appear within a day of exposure.  Rarely persons may develop signs and symptoms 2 days following exposure but more typically it takes 3 or more days to become symptomatic.

As far as your contacts are concerned, what you describe is limited to masturbation and that your partner straddled you during the activity does not increase your risk.  masturbation is safe sex and you need not worry about getting an STD in this way.

Thus, to summarize:
1. No need for worry due to incidental contact.
2.  Nothing you have described warrants testing
3.  A benign, non-STD skin process.  If you want it identified completely or removed, I suggest you see a dermatologist.

Hope this helps.  EWH

Thank you for your reply, you have answered all of my concerns.  I intended to ask two separate questions, one about the bump, and the other about the risk associated with my partner straddling me during masturbation.  

Regarding the bump, I figured it was nothing but I was reassured with your answer.  I was particularly concerned about the incidental contact while she straddled me and again was pleased to learn that I shouldn't worry.  
Thanks again
