Question give or take a few HIV...?

Hey im having the hardest time near this..can anyone help me out a bit.
Place these sexual comings and goings from low risk to high risk for contracting HIV/AIDS when lowest risk is (1) and topmost risk is (11). (Terms are a mixture of scientific language, romantic terms, and street language -- as you will most likely come across adjectives of these language types while working near the general population).

oral sex

. mutual masturbation

. coitus as insertive partner
coitus as open partner

holding hands

huggingQuestion give or take a few HIV...?
1. holding hand
2. hugging
3. frottage (rubbing genitals against another person's body)
4.mutual masturbation
(all no risk, although MM could be a theoretical risk, depending on what happen to any ejaculate).
5. Golden shower (theoretical risk but no reports of transmission)
6. French kissing (one "possible" case identified but token risk)
7. oral sex (very occasional cases reported, mainly quick to respond oral sex with ejaculation, and possible co presence of other infections such as gonorrhoea)
8. vaginal or anal sex using a condom (minimal risk if condom remains intact, possible risk if it doesn't)
9. insertive vaginal sex
10. alert vaginal sex
11. anal sex, especially receptive
(the end three all thoroughly documented modes of HIV transmission).
What's frottage?
I would put them contained by this order...assuming you have them numbered from 1-11.
