I had an encounter with a massage with a massage parlor. She did a full naked body massage on me. Mid way through she offered to provide additional sexual services which i declined, however she did masturbate me.

At one point she did rub her vagina against my left thigh, not my penis (I made sure we did not rub our genitals against each other). This morning i remembered that the thigh she rubbed against had a few minor cuts on them that were not fresh from the day but maybe from 2 or 1 day ago. 

Do these cuts pose any form of risk for STD transmission? i am worried about herpes and syphillis from the rubbing against my thigh.

does this count as apposition as our genitals never made contact but wondering if a cut does and it being my lleft thigh make a difference?

If our genitals braised each other's i can be sure there was no rubbing of genitals against one another except for my thigh to be rubbed against her vagina

I have a partner, is it safe to resume sexual activity. I don't want to pass anything on. I thought i was being safe overall as i understand a massage to be safe risk.

For all practical purposes, this was a zero risk event for any and all STDs. I would not consider this genital apposition, and in any case even that has little risk. Having skin nicks or cuts is one of those things that people worry about and you can find discussed as risks in various online sources, but you won't see that on knowledgeable, professional, or professionally moderated sites. I see no reason to not continue unrproocted sex with your regular partner.

I hope these comments are helpful. Let me know if anything isn't clear.
