For me I'd have to say no but I don't have a P style plug yet either. When I have it in it just heightens my orgasm. I don't know why it just does. The larger the better. If your just experimenting by your self relax and just start small, finger size then work your way up. It usually wont happen overnight. I have purposely pressed against my P spot with a plug, and it did feel good but no O yet. Having said all this, I've never had anything larger than 1.8 across. I'm working on 2" because I have a plug 2 inches that I would love to get in there but the darn thing is stubborn. That will be my max unless my woman wants to ever get really kinky. As far as not wanting something that looks like a dick just go for it, I used to have the same hang up but it doesn't mean your gay or bi. Thats when I have the best O because you are in control of where it goes. Their usually soft and flexible also, I recommend one with a suction cup. Good luck and enjoy.
