Hi I know thread is old but here is my two cents. I like having my ass stimulated. My GF and I are pretty open to trying new things. Up till now we have a couple vibes that she uses on me while she gives me a handjob or blowjob, but we are actively looking at getting a strap on. The idea is fun to her and rather exciting. If anyone is curious as to how it goes fell free to let me know.
