I'm sorry, I do not buy the story that you were an unwilling partner in vaginal penetration. It is not plausible. But that's not the point (and I'm not going to debate it with you anyway). The issue is whether you could have acquired an STD. The answer is almost certainly not, since you wore a condom, oral sex is low risk or all STD, and of course hand-genital contact is zero risk. It is possible for herpes or HPV to be transmitted by skin contact above where the condom covers, but it is uncommon for any single exposure. How uncommon? I haven't a clue; there are no data. But rare enough so that all you need to do is look out for symptoms, like penile blisters that become scabs or open sores.
As to the exposure 6 weeks previously, you used a condom. Thus zero to very low risk, just as at the massage parlor. There are no data to otherwise estimate. But anybody who is sexually active outside a permanent, mutually committed relationship should have routine STD and HIV tests from time to time, like once every year or two. So if you haven't been tested recently, this would be a good time, since it's on your mind.
