I haven't had sexual contact for about six weeks now. Around the time of my last sexual activity, I noticed about eight small bugs on my right arm. They were attached to the hairs on my arm and I had to pull them off with some force. At the time, I described them as "very small and spider-like". There was no itching, no rash, and no other 'signs' of lice. I removed those eight bugs and never saw them again. There were none in my pubic area at all.
That was about six weeks ago. Then yesterday, I noticed another one of these bugs in my pubic region, crawling very quickly. I picked it off and flushed it. Since then, I have been looking for them and have found about five or six more (sometimes I look and find none, other times I find one and pick it off). These look similar to the bugs I saw last time, only a little bit smaller. I have NO itching whatsoever. There are very few of the bugs and I don't see anything in the lining of my clothes, not even with a magnifying glass. The bugs don't look exactly like the pictures of public lice that I have seen online, though they are very small, so it's hard to be sure. I can't tell if these bugs have four or six legs.
I assume that these are *probably* pubic lice, just because I don't know what else they would be. However, it seems very odd that I would have them popping up now when it's been a month and a half since I was last sexually active, and since I have so few of them and with no itching at all or other signs. Is there anything else that this could be? I don't want to treat myself for pubic lice (i.e. apply the recommended shampoo) if I have a different problem.
(Since yesterday, I have only seen these bugs in or just beside my pubic hair, which I trimmed very short in order to get a closer look. They aren't on my arm now or anywhere else on me as far as I can tell.
